Constant temperature constant humidity EW-330

EW-330 Temperature & Humidity Controller

Capable of accurate temperature and humidity monitoring, this product helps prevent condensation and ensure that ambient temperature and humidity meet specific operating requirements. Featuring digital display of set value and measured value, this product allows users to set control values of temperature & humidity manually. Humidifying and dehumidifying modes are optional; heating, dehumidifying and fan cooling can be set easily. Open circuit alarm of heater, cooler and dehumidifier. Open circuit alarm of transducer and auto load cut-off to prevent long-term overloaded operation resulted from transducer open circuit.

Technical Specification

1. Upper nixie tube is to display temperature or relevant parameters; lower nixie tube is to display humidity
or relevant parameters;
2. Range of temperature control: -39?~98?. Resolution: 1?; precision: ±1?. Normally, current temperature
measured is displayed. Heating or cooling can be set easily. Pick-up of relay: the indicator light is ON;
heating :the indicator light is kept ON; cooling: the indicator light is twinkling.
3. Range of humidity control: 20%RH~98%RH. Resolution : 1%RH; Precision: ±5%RH. Normally, current
humidity measured is displayed. Humidifying or dehumidifying can be set easily. Pick-up of relay: the
indicator light is ON; humidifying: the indicator light is kept ON; dehumidifying: the indicator light is
twinkling.
4. Three control relays: 1 temperature relay, 1 humidity relay, and 1 fan relay. The fan relay and temperature
relay are synchronous.
