The HTemp-485 (T3411) is HW Group’s wired temperature and humidity probe with Modbus RTU output and a built-in LCD showing live readings at the sensor itself. It measures from -30°C to +80°C and calculates dew point, absolute humidity and specific humidity from the combined readings — useful anywhere condensation risk matters as much as the raw numbers.
As an RS-485 Modbus RTU device it runs long cable distances on a simple two-wire bus, so one Perseus unit can poll a chain of these probes across a plant room, warehouse or production floor. It works equally well standalone with any Modbus master. IP65-rated electronics in an IP40 housing allow sheltered outdoor use.
