OTEK's 1PM is our smallest LED Digital Panel Meter (and Loop Powered). The unit is only 1" x 1.3", with 0.33" LEDs.
OTEK brings you the World's smallest LED Digital Panel Meter (and Loop Powered). That is why we call it the 1PM! The size does not affect its reliability, performance and accuracy and we even managed to add the over-range indicator above the MSD so you know you have exceeded the full scale range. We added the negative sign indicator ("-") below the MSD so you know your signal is negative. You can adjust the Zero & span (+30% range) via 12 turn potentiometers on the rear and connections are made via standard 0.1" center headers for P.C.B. or panel mount. For panel mount, a polarized ? lter is available on request. The 1PM is a typical example of OTEK's Custom and Semi-Custom capabilities. If it can be done, we can do it!
