Our Products
Leading Manufacturer, Supplier & Retailer of Humidity Indicators, Humidity Indicators/Controllers, RPM Indicators, Temp. Indicators and Frequency Indicators.
HC 2000 is a brainchild of Nippon Technologies. State-of -the-art micro controller design is a high performance solution for various HUMIDITY applications. It accepts two 4-20 mA inputs. One for Humidity and another for Temperature. Generally the signal comes from humidity transmitters. Typical applications
| Input | From Humidity/Temperature Transmitter. (Dry / Wet bulb input available on request) |
| Display | 2 sets of (4+4) digit diaplay. Upper for Temperature and lower for Humidity |
| Range | Humidity 0 to 96.0 % RH Temperature -20 to 80.0 ºC, depending on type of Transmitter. |
| Resolution | Relative Humidity 0.1 RH Temperature 0.1 ºC |
| Output | 2 Relays. A) Humidity Control: One relay for Humidification, second for relay for Dehumidification. B) Temperature Control: One relay for cooling (Comprosessor / Blower), Second relay for Heating (Heater) |
| Control Accuracy | ± 3 % for Humidity / ± 0.25 % for Temperature |
Six point selection switch is available to select the channels. The selector switch is heavy duty & zero contact resistance.
