HE-960CW

Panel-mount type 2-channel conductivity meter (conductivity meter)

Ideal for pharmaceutical water management and temperature monitoring during Steam-In-Place (SIP) sterilization.

An ideal conductivity meter for water quality management from pure water to 2000 μS/cm. Specifically designed for the pharmaceutical industry, the water quality determination capabilities are compliant with USP<645> (U.S. Pharmacopeia), making it ideal for the management of pharmaceutical water such as water for injection (WFI). Offering a lineup of sensors for pharmaceutical manufacturing processes that comply with the pharmacopoeias (USP, EP) of various countries, as well as sensors suitable for sample properties. The use of a panel mount transmitter allows for cost reduction at the time of installation.

Transmission output	Number of outputs: 4 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.)

Output contents: selectable from the selected measurement, USP assessment,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. Output contents: selectable from the selected measurement, USP assessment,anomaly alarm and maintenance. (However, R1 and R2, and R3 and R4 share the common contacts respectively.) Contact operation (operation between C and NO for R1 to R4) When selected measurement, USP assessment, or maintenance is selected in output contents: Contact point becomes “CLOSE” at control operation and “OPEN” at normal state (including power shutdown). When anomaly alarm is selected in output contents: Contact point becomes “CLOSE” at normal state and “OPEN” at anomaly state (including power shutdown). (When between C and NC is used with R4, contact point becomes reverses state with that of between C and NO.)
Communication output	RS-485 input/output
Calibration function	Conductivity: Based on the specified compensation coefficient for cell constant (parameter input). Temperature: Calibrated by comparing with the reference thermometer. TDS: Conversion using a user-defined coefficient value (0.30 to 1.00).
