The manufacturer uses exactly the same model number for both devices, but there are significant differences:
The version referenced as 'type 2' on this website contains a dedicated metering chip able to calculate power use more accurately for a wider range of appliances. The version referenced as 'type 1' on this website - uses an older analog circuit design.
Easiest way to determine which meter from the label:
- 'type 2' has label text: "Battery 3X1.5V"
- 'type 1' has label text: "Battery 2X1.5V"
The 'type 2' is easily identified by the small depressions on both sides of the larger battery cover. In the picture below the Type 2 is shown first (on the left).
