Trumeter APM-FREQ-APO APM Frequency Hz Meter Positive LCD Digital/4-20mA Outputs

The APM Frequency Meter accurately measures frequency and speed from DC pulses, supporting 2-400Hz input with 0.5% accuracy. It includes 20-point non-linear scaling for non-linear sensors. Its LCD display combines analogue readability with digital precision, featuring a large readout, 40-segment bar graph, and color-changing backlight for instant feedback. Users can customize scale, range, alarms, and messaging via the free APM configuration software. Pair with the IoT Gateway for Trumeter Cloud access, enabling remote monitoring, data logging, and alerts via SMS, email, or online. Two independent outputs can function as digital (open collector) or analogue (4-20mA). The positive display is optimized for bright environments with black figures on a color-changing background.
