This is a detection kit for easily determining the presence of asbestos (asbestos) at a concentration of 2% or more in materials classified as Level 1 (asbestos-containing sprayed materials), Level 2 (asbestos-containing fireproofing materials, asbestos-containing insulation materials, asbestos-containing thermal insulation materials), and Level 3 (other asbestos-containing molded boards) according to the "Manual for Thorough Measures to Prevent Asbestos Dispersion and Leakage" (Ministry of Health, Labour and Welfare, Version 2.20, March 2018). Since there is a possibility that the measured object contains asbestos, please ensure to wear protective equipment to prevent exposure during handling. This product uses patented technology developed by the Hiroshima Prefectural Institute of Technology Health and Environment Center (Patents No. 6781441 and No. 6864892) and is produced under a licensing agreement with Hiroshima Prefecture.

This product is a set of separation concentrator and pack test. It can be applied to wastewater management and soil and groundwater pollution measures. Cadmium contained in the water sample is separated and concentrated on the filter, and then measured using the pack test after elution.

• Measurement and Inspection

The "Anionic Surfactant Measurement Set" can measure anionic surfactants in tap water, river water, etc., in just about 3 minutes. The measurement range corresponds to the standard value of the Water Supply Act (0.2 mg/L or less). 【Features】 ■ Measures anionic surfactants in just about 3 minutes ■ Corresponds to the standard value of the Water Supply Act (0.2 mg/L or less) ■ Number of measurements: Approximately 50 times ■ Package dimensions: Approximately 165L × 110W × 65H mm ■ Package weight: Approximately 240g

The "Digital Pack Test Multi SP" is a portable multi-parameter water quality meter equipped with the functions of a visible spectrophotometer. List of measurement items https://packtest.jp/dpm-mtsp-item It can perform concentration measurements, absorbance measurements, spectral measurements, and time scans, allowing for simultaneous concentration measurements of up to 4 samples and 4 parameters. Additionally, the calibration curve is pre-entered and the touch panel makes operation easy. The latest calibration curve data can be downloaded from the website. 【Features】 ■ Lightweight and portable ■ Easy operation ■ Sample volume 1.5mL ■ Sample products available ■ In addition to the dedicated cup (1.5mL cell for Digital Pack Test), 10mm cells (rectangular) and semi-micro cells can also be used.

• Water quality/pH measuring device

The "Pack Test Arsenic (Low Concentration) Set" is a simple water quality analyzer that can measure arsenic levels from the environmental standard of 0.01 mg/L to the uniform discharge standard of 0.1 mg/L on-site. It is applicable not only for managing environmental water such as groundwater and factory wastewater but also for leaching tests under soil contamination countermeasures law. Arsenic contained in the water sample is separated and concentrated on a filter, and then measured using the pack test after elution. 【Features】 ■ Membrane separation and concentration device + pack test set ■ No interference from phosphoric acid ■ No generation of arsine ■ Mercury-free ■ Can also be measured with separately sold digital pack test series (measurement range: 0.009 to 0.2 mg/L)

• Water quality/pH measuring device

The "Pack Test Lead Set" is a set of separation and concentration apparatus plus a pack test. It separates and concentrates lead from other metals using a highly selective molecular recognition gel, while measuring the red color of the complex formed between PAR and lead. This allows for selective measurement of lead, as well as the ability to measure low concentrations at the uniform wastewater standard level (0.1 mg/L). Additionally, by increasing the flow rate, measurements can also be taken at the environmental standard level (0.01 mg/L). 【Features】 ■ Set of separation and concentration apparatus + pack test ■ Measures the red color of the complex formed between PAR and lead ■ Capable of measuring low concentrations at the uniform wastewater standard level ■ Can also be measured with the separately sold digital pack test series (Measurement range: 0.03 to 0.5 mg/L)

This product is a high-sensitivity type of simple water quality analyzer that colors trace components in the test water, collects and concentrates them on a chip, and measures them colorimetrically. If the coloration of the test water inhaled into the pack test tube is faint and unclear, subsequent concentration operations allow for measurements at concentrations 25 times lower than conventional methods. The development of a small chip loaded with a membrane that serves as a collection medium enables simple and rapid concentration operations. (Patent obtained) 【Features】 ■ Achieves 25 times higher sensitivity than pack tests ■ Applies technology to collect trace coloring products as hydrophobic ion aggregates on a porous membrane ■ Enables simple and rapid concentration operations

The "Digital Pack Test®" is a handheld single-parameter water quality meter. There are a total of 38 models (including ammonium, nitrate, residual chlorine, cyanide, etc.). The water sample (1.5ml) that has been color developed using a pack test is transferred to a dedicated cup for measurement, and the measurement results are displayed as concentration (mg/L). 【Features】 ■ Handheld type ■ Compact and lightweight, suitable for field measurements ■ Easy operation with pre-entered calibration curve ■ Data recording automatically saves up to 50 entries ■ Water sample of 1.5ml

The "Pack Test® Standard Type" is a very simple water quality testing device. It contains a single-use measurement reagent sealed in a polyethylene tube with a diameter of 1 cm and a length of 7 cm. By drawing the water to be tested into the tube, the measurement reagent reacts with the target component, resulting in a color change. Comparing the color change to the provided standard color allows for a simple determination of concentration.
