The Resol HE Check is the perfect tool for testing new ERP high efficiency pumps and controllers. Current test meters do not have the ability to measure PWM signals meaning that effective diagnosis of faults is very difficult.
The HE check is very easy to use, it can measure PWM and 0-10v outputs from controllers and it can also generate its own variable signal (40 to 2000 Hz) to fully test HE pumps from all the leading manufacturers.
The HE Check comes with a set of measuring and signal cables for different pumps and controllers. The storage case and the robust housing make the HE-Check ideal for daily application.
The HE Check is not just limited to Solar Thermal – it has many uses throughout the heating/maintenance industry and will become an important part of your toolkit.
