Description
The HHM290 has been discontinued. Please see the HHM9007R as possible alternative or contact our Temperature Engineering department.
This product has an Interactive Showcase. Click on the icon to the left to experience it.
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.
The HHM290 is being [phased out. Please see the HHM9007R for complete the details on the newest model, or contact our Pressure department for more information..
