Calibration : May be available depends on probes
JCSS Accredited Calibration : May be available depends on probes
This model is one of the Temperature/Humidity Transmitter SK-RHC series with current output (4 to 20mADC). Choose one of three types of probes sold separately as you like. AC adapter is available with extra cost.
Photo shows a combination of this main body and a plug-in type probe SK-RHCS-1. (Cat. No. 8921-00).
Instruction manual
Feature
■ Select either one of the following output signals when you order: voltage, electric current, or RS-485. Four types of external indicators are also selectable.
■ Select the probe such as plug-in type or with-sensor-cord type when you order.
■ Equipped with Hi/Lo alarm
Description
■ A probe must be purchased separately.
■ Use isolated wirings for temperature and humidity terminals for devices connected to SK-940A-I because all the positive side of the circuit is unified.
Install an isolator if said terminals are grounded together.
