I have registered the web flyer for the particle counter!!

6 particle size, high-performance compact! A side light scattering micro-particle measuring instrument that achieves long lifespan and quiet operation.

The "7301" is a real-time meter that displays pulses on the screen every second, showing particle concentration and equivalent mass concentration (in µg), and provides various communication functions as a light scattering method for measuring fine particles. The dedicated printer is common across all models. With the smart battery feature, it can measure continuously for a month on a single charge while left on-site. Continuous measurement lasts for 6 hours. The IMS software allows for external device control, data collection, and real-time graphing via USB or Ethernet on computers and other devices. 【Features】 ■ Real-time meter with particle count displayed in graphs every second ■ Particle counter particle size: 0.3μm to over 10μm ■ Environmental sensor: TRH (temperature and humidity sensor probe - optional) ■ PM mode µg/m³ (mass concentration equivalent) ■ ISO, GMP, FDA compliance, and reporting functions ■ Brushless motor pump for quiet operation and long lifespan *For more details, please refer to the PDF documentation or feel free to contact us.

User-adjustable particle size settings! Light scattering method particle counter compatible with 6 particle sizes for large particles.

The "8506 Series" is a light scattering method particle counter that measures particle sizes ranging from 0.5μm to a maximum of 30.0μm and counts, displaying the measurement data for six set particle sizes (channels) along with temperature and humidity data (optional) simultaneously. Using the count data, it calculates the mass concentration of particles below the specified particle size based on user-defined parameters for density and refractive index, displaying PM concentration in μg/m³. The built-in Pulse Height Analyzer ensures reliable compliance. 【Features】 ■ Real-time meter with particle count graph displayed every second ■ High concentration support across a wide particle size range ■ User-friendly large touch panel and icons ■ Data memory for 45,000 samples ■ Remote control and graph plotting via IMS (standard software) ■ Equipped with a smart battery ■ Long-life laser with a durable optical system *For more details, please refer to the PDF document or feel free to contact us.

All operations can be performed with touch panel icons! 3-channel particle counter.

The Particle Plus model '8303' measures particle sizes and counts of 0.3μm and above, displaying measurement data for three set particle sizes (channels) along with temperature and humidity data (optional) simultaneously using a light scattering method. It is operated entirely via touch panel icons. By setting density and refractive index (both user-defined) as parameters from the count data, it converts the mass concentration of particles below the specified size and displays PM concentration in μg/m³. 【Features】 - Real-time meter with particle count displayed in a graph every second - Wide particle size range of 0.3 to 25μm and capable of high concentration (up to general environmental levels) - Large color touch panel with easy-to-read and understand icons - Simultaneous measurement, display, and output of particle count concentration, mass concentration, and temperature difference (optional) for differential and total particle sizes - Data memory capable of storing 45,000 samples - In battery mode, it can be used continuously for 10 hours on a single charge For more details, please contact us or download the catalog.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily visible at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

PERI products are used at construction sites around the world. This time, we would like to introduce the construction work of the "Dunajec Road Bridge" spanning the Dunajec River in the town of Nowy Targ in southern Poland. The road bridge was planned to be constructed using a balanced cantilever method, dividing the cantilever beams starting from each pier into 10 segments. A particular concern was to strictly adhere to the concrete pouring cycle for each segment. To achieve this, a balanced cantilever carriage (VBC) equipped with a hydraulic advance system and an automatic formwork stripping function was adopted. By utilizing the VBC, it became possible to pour concrete for segments up to a maximum length of 5 meters in a single cycle, allowing for efficient and timely construction. PERI products: 1. TRIO Panel Formwork 2. VARIO GT24 Wall Formwork 3. PERI UP Flex Modular Scaffold 4. VST Heavy-Duty Shoring Tower PERI Japan Co., Ltd.

At a major purchasing specialty store located in Kanagawa Prefecture, we have introduced our commercial aroma diffuser rental service "MajestaFragrance," enhancing the store's atmosphere with fragrance. Installed models: MFmini (4,400 yen per month) × 2 units Adopted fragrance: Freesia Pear To ensure that customers visiting the store can relax during their appraisal and consultation time, we have implemented space branding with a "refined and approachable scent." The fragrance used is "Freesia Pear," which pleasantly spreads the freshness of fruity pear and the vibrant aroma of freesia. It warmly welcomes customers with a clean and high-quality scent. The "MFmini" introduced this time is a compact yet powerful diffuser known for its strong diffusion capabilities. It blends smartly into limited installation spaces such as reception counters and customer service areas, efficiently delivering fragrance. At Majesta Fragrance, we offer optimal diffuser models and fragrance suggestions tailored to the size of the store, type of business, and interior atmosphere. A "free trial installation" is also available before signing a contract.

We will be exhibiting at the "Osaka Industry Exhibition 2026" held at MyDome Osaka from October 14 (Wednesday) to 15 (Thursday), 2026. We will introduce our stress check, health management system, reservation and reception system, and interview system.
