Technical Description |
 |
|
| The unit contains sensors with digital displays to measure temperature, pres-sure and flow rate required for measurements and demonstrations on heating and sanitary systems. Various water circuits and a gas circuit can be selected. It is possible to adjust settings and investigate the performance effects while testing the function of external heaters (e.g. gas heaters, combination heaters, instantaneous heaters). An integrated plate heat exchanger allows the measur-ing system to operate without additional loads. Measured values can be trans-ferred to a PC. HL 820 can be attached to HL 090. |
