Multimeter HP-90BS with rechargeable battery and solar panel
Digital multimeter with automatic selection of measurement limits. Temperature measurement. Overload protection. True RMS function. Built-in solar cell and battery as power source.
The standard set of measurement functions has been expanded with temperature measurement. For this, the device is equipped with a K-type thermocouple in a closed design, in a sheath made of a stainless tube with a diameter of 4 mm.
The device is protected against overload by a self-resetting fuse. The current input for a measuring range of 100A is protected by a fast-acting fuse.
Algorithm for measuring True RMS.
Function of testing batteries with voltage from 1.5V to 12V, load current ~ 25mA.
The main feature of the device that attracts attention is that the multimeter is powered not from the traditional "Krona", but from the built-in NI-MH battery with a voltage of 3.8 V. For constant recharging of the battery, a solar panel is installed in the upper end of the device. There is also the possibility of charging from the mains (charger is included in the kit)
