![[Data] Shirutoku Report No. 39 #Evaluation with Curve Tracer](https://image.www.ipros.com/public/product/image/746/2000692242/IPROS03536288885189074109.jpeg?w=280&h=280)
Customization suitable for the measurement environment is also available! Introducing the automatic measurement system with curve tracer.
★★Shirutoku Report: Useful Information You Should Know★★ What kind of measuring instruments do you use when evaluating the electrical characteristics of semiconductors like MOSFETs and bipolar transistors? While there are dedicated testers, curve tracers that allow for easy evaluation are also convenient, right? However, when using a curve tracer, have you ever thought, "There are so many evaluation items, it's a hassle to operate manually..." or "There are so many evaluations, it would be great if it could be operated more easily..."? If these needs can be met, you would be freed from the enormous evaluation time. Therefore, we would like to introduce the 'Automatic Measurement System for Curve Tracers.' For more details, please take a moment to read on. [Contents] ■ Automatic Measurement System for Curve Tracers *For more information, please refer to the PDF document or feel free to contact us.
Real-time centralized monitoring of water levels at multiple locations, such as rivers and reservoirs, where flood and inundation monitoring is necessary, while keeping introduction and operational costs low.
As sudden and localized disasters described as "the largest in recorded history" and "once in 50 years" occur, monitoring of reservoirs and rivers is becoming increasingly important. Therefore, by installing measuring devices (monitoring posts) in more rivers, we have combined the latest technologies such as ICT and IoT with existing elemental and general-purpose technologies to accurately grasp flood situations and quickly and accurately understand the anticipated impacts, thereby achieving a solution that reduces not only the introduction costs but also the TCO (total cost of ownership). The measurement data collected from the devices is uploaded to the cloud via LoRaWAN, and when thresholds are exceeded, notifications are sent to registered email addresses. Additionally, it is possible to monitor in real-time through a web browser and download measurement values, allowing for the confirmation of multiple sensor readings from a distance. This not only reduces the time staff need to physically visit locations at risk of flooding during heavy rain or earthquakes but also eliminates the risk of staff being affected while on patrol.

![[Case 6] Water quality monitoring of nearby commercial wells associated with foundation pile construction (Fiscal Year 2009)](https://image.www.ipros.com/public/product/image/caf/2000117111/IPROS4491989263386994157.gif?w=280&h=280)
As experts in soil and water, we comprehensively support groundwater quality monitoring.
When the construction of a structure's foundation reaches an aquifer, there are concerns about the impact on the water quality of nearby wells that draw from that aquifer. This is especially critical for commercial wells, which require delicate management and emergency response measures. Central Development Co., Ltd., as an expert in "soil" and "water," provides comprehensive support for groundwater quality monitoring, including real-time monitoring services, planning of observation well placements, setting management standards, and developing emergency response manuals. For more details, please contact us or refer to our catalog.
Introduction to groundwater level lowering work and monitoring of water levels and water quality associated with mountain tunnel construction.
The "Monitoring Cases of Water Level and Water Quality" introduces construction examples conducted for safe tunnel construction in mountainous areas. We carried out groundwater level lowering work using the "Deep Well Method," and monitored the water level, pumping volume, and the water quality of the discharged groundwater. We also monitored the water levels of existing observation wells in the surrounding area. To eliminate cumbersome wiring work, we used "specific low-power wireless," achieving a reduction in work processes and costs. [Features] ■ Monitoring of groundwater levels and water quality ■ Reduction of work processes and costs through the use of wireless equipment *For more details, please refer to the PDF materials or feel free to contact us.
Achieves a diameter of 14 mm with a built-in amplifier, can also be inserted into PVC pipes for deep well water level measurement.
The GWL-type water level gauge converts water pressure into an electrical signal using a pressure-resistant element and outputs DC 1-5V through a built-in amplifier. It can be measured with a typical voltage input data logger. This is an atmospheric pressure compensation type water level gauge that eliminates measurement errors caused by fluctuations in atmospheric pressure using a reference pipe within the cable.

The construction method is easy, and maintenance is simple! A quartz water level gauge that allows for clock calibration using GPS.
The "QS Series" is a pressure-type water level gauge that utilizes quartz oscillators, which serve as the frequency standard for clocks and communication devices. It applies water pressure, which changes with the water level, to the quartz oscillator, and derives the water level from the oscillation frequency that varies accordingly, enabling high-precision measurements. Additionally, it eliminates conversion errors due to aging changes in components like diaphragms commonly found in traditional pressure-type water level gauges. With a measurement range of 10m to 70m using a single sensor, it is suitable for use in rivers, dams, reservoirs, and tide levels, offering excellent cost-effectiveness. 【Features】 ■ Maximum accuracy of 0.01% F.S. High precision and reliability from quartz oscillators ■ Easy installation on embankments and structures ■ Simple maintenance management ■ GPS (optional) for clock calibration *For more details, please refer to the PDF document or feel free to contact us.
