The JWSK-8 series temperature and humidity transmitter is an industrial-grade product with multiple analog and network output options. It can measure temperature and humidity in the range of -40℃ to 120℃. Its features include a large LCD display for temperature and humidity, alarm status, zero point correction function, optional relay output, and optional network RS485 or RS232 output.
The JWSK-8 series temperature‑humidity transmitter is an industrial‑grade sensor that measures temperature from –40 °C to 120 °C and relative humidity from 0 %RH to 100 %RH. It offers multiple output options (0‑5 V, 0‑10 V, 4‑20 mA, RS485 or RS232) and a 128 × 64 LCD display.
The manual provides detailed installation steps for wall‑mount, pipe‑mount and split‑type units, explains menu navigation, communication settings, alarm configuration, and includes a fault‑diagnosis guide with Modbus protocol examples. This manual is written in Chinese.

Press the '/' key to adjust the address value (0‑127) and confirm with the Enter key.
The default settings are COM1, 9600 bps, 8 data bits, 1 stop bit, no parity.
It is recommended to calibrate the transmitter at least once a year to maintain measurement accuracy.
Check that the wiring is correct and secure; a zero output may indicate a wiring error or that the sensor is out of range.
