The "AQM-100A model" is a compact and lightweight panel-mounted resistivity meter. It is capable of measuring near the thermal sterilization process of ultra-pure water, with transmission output (DC 4-20mA) and alarm output (2 circuit c contacts), and displays the sample water temperature. It measures the resistivity of ultra-pure water (0-20MΩ·cm) in semiconductor plants, with a wide temperature compensation range of 0-100℃. 【Features】 ■ Compact DIN96 size ■ Can connect two detectors (optional) ■ Equipped with cell constant adjustment function ■ Can set two alarm points ■ Transmission output is an insulated DC 4-20mA *For more details, please refer to the PDF materials or feel free to contact us.

The "AQM-210A model" is a compact and lightweight panel-mounted 2-channel resistivity meter. It measures the resistivity of ultra-pure water (0 to 20 MΩ·cm) in semiconductor plants with a wide temperature compensation range from -5 to 120°C. It displays transmission output (DC 4-20mA, 2 circuits) and alarm output (2 circuits with contact points), as well as the sample water temperature. 【Features】 ■ Compact DIN96 size ■ Measurement near the thermal sterilization process of ultra-pure water is also possible ■ Equipped with cell constant adjustment function ■ Standard RS-232C digital communication output *For more details, please refer to the PDF document or feel free to contact us.

Introducing a two-electrode conductivity detector that can accommodate a wide measurement range from ultra-pure water used in semiconductors and power plants to river water and industrial wastewater. We offer various installation methods, including pipe insertion, immersion, and submersible types. There are four cell constants available: 0.01/cm, 0.1/cm, 1/cm, and 10/cm, allowing measurements from ultra-pure water below 0.2μS/cm to wastewater up to 10mS/cm (A5/A6 models). 【Features】 ■ The insulating seal materials for the inner and outer electrodes are made of glass hermetic and Teflon (PTFE), providing high heat and pressure resistance (A5/A6 models). ■ The connector box is integrated, making it easy to connect with the converter and detach the detector. ■ The compact and lightweight AR4/AR5 models for pure water have no restrictions on installation orientation. *For more details, please refer to the PDF materials or feel free to contact us.

This is a multi-type portable water quality meter that allows for the measurement of "pH," "ORP," "electrical conductivity," and "dissolved oxygen" through probe replacement. Available in a 2-channel type MM-42DP and a 1-channel type MM-41DP! The measurement of dissolved oxygen adopts an "optical method"! With a waterproof structure and backlight, it can be safely used in the field. ◎ You can view detailed specifications and more from the "PDF Download."
