CHINO HN-Ekseries Wall-mounted thermo-hygrometer HN series

A thermometer and hygrometer for air conditioning management and measurement that "measures accurately", reduces the effects of heat conduction from the mounting surface and achieves high-precision measurement, only the sensor unit can be replaced, slim design that can be installed anywhere, equipped with a high-precision sensor, ▼ Humidity can be measured at ±2%rh over a wide range, ▼ Uses a platinum resistance thermometer (accuracy: ±0.3°C) for the temperature sensor, adopts a sensor unit replacement method, easy installation, ▼ Can be installed in a general-purpose recessed box *1, ▼ *1 Mounting pitch 83.5mm (JIS C 8435), reduces the effects of heat conduction from the mounting surface, ▼ Installed with a thermoplate that cuts off the inflow of heat from walls and pillars with high thermal capacity
