Panel-mount type 2-channel electric resistivity meter (resistivity meter)

HE-960RW

For control and monitoring treatment and production processes of pure water and ultra-pure water.

A high-grade resistivity meter that significantly improves critical temperature compensation performance for resistivity measurements of UPW (ultra-pure water) and high-temperature pure water, through adopting a newly designed temperature measurement circuit. Highly stable resistivity measurements are achieved through resistance to changes not only in water temperature, but also in ambient temperature.

Temperature: 0℃ to 100℃ (Select your desired decimal point from 0, 1, and 2 digits.)
Repeatability Within ±0.1% of the full scale (in equivalent input)
Linearity Within ±0.5% of the full scale (in equivalent input)
Transmission
output		 Number of outputs: 2
4 mA to 20 mA DC/0 mA to 20 mA DC, input/output isolated type
Maximum load resistance: 900 Ω
Transmission output range: Freely selectable within the measurement range
(Negative terminals of each transmission output channel are connected inside and thus have the same electric potential.)
Contact output Number of outputs: 4
Alarm contact outputs (R1, R2, and R3)
　　Contact type: relay contact, SPST (1a)
　　Contact rating: 240 V AC, 3 A and 30 V DC, 3 A (resistance load)
　　Contact function: selectable from the upper/lower limit action (ON/OFF control), delay, and hysteresis
　　Selectable from the selected measurement, anomaly alarm, and maintenance.
Alarm contact output (R4)
　　Contact type: relay contact, SPDT (1c)
　　Contact rating: 240 V AC, 3 A and 30 V DC, 3 A (resistance load)
　　Contact function: selectable from the upper/lower limit action (ON/OFF control), delay, and hysteresis
　　Selectable from the selected measurement, anomaly alarm, and maintenance.
　 (However, R1 and R2, and R3 and R4 share the common contacts respectively.)
Calibration function Specific resistance: Based on the specified compensation coefficient for cell constant (parameter input)
Temperature: Calibrated by comparing with the reference thermometer
