Portable heat flow meter/heat flow meter HFM-201

Heat flow meter
A thermal instrument composed of a heat flow sensor (or heat flow probe) connected to a measurement indicator. When in use, the sensor can be placed inside the insulation structure or attached to the outer surface of the insulation structure to directly measure the heat (cold) loss value.
Heat flux sensor; HFT
A device that measures the heat flux density through a board with a determined thermal resistance by generating a temperature difference on it. Its output potential（V）Compared to the heat flux density through sensors（q）Directly proportional.
It consists of a core board, a surface temperature difference detector, and a panel that provides protection and thermal damping.

Portable heat flow meter/HFM-201 main features:

1. The heat flow value (W/m2 or kcal/m2h) and temperature (° C) can be switched for display.
2. The temperature sensor can be switched to a chromium aluminum thermocouple or a copper copper nickel thermocouple.
3. The single channel heat flow meter includes a TR2-B heat flow sensor.
4. It can store 20 sets of files, totaling 100 pieces of data.
5. Two power supply methods: dry battery or AC power.
6. Single channel heat flow meter standard configuration RS-232C interface.
7. The standard configuration of a single channel heat flow meter includes a portable outer box.
8. The single channel heat flow meter can be equipped with an optional printer to print the results.
