The HHM290 is a low cost digital multimeter & thermometer. It has a built-in infrared sensor and laser sighting for non-contact temperature measurement. The optical field of view is 10 to 1. This multimeter also measures and displays voltage, current, resistance, inductance, capacitance and frequency. It also has dual type K thermocouple inputs (non-isolated) for temperature measurement. Special features include T1-T2, min, max and average readings, manual/auto range and a built-in timer.
