Why Choose the APM Micro Meter
The APM Micro Meter measures DC current measurement in microamps and is essential for applications demanding precision and reliability. The high-resolution 0-200 µA detects minor current changes to 0.1% accuracy making it ideal for monitoring sensitive processes that require fine measurements or where minor fluctuations can be critical. Applications include laboratory and other precision instrumentation, circuit testing, sensor calibration and low-power electronics.
The unique display combines the instant readability of an analog meter with the precision and functionality of a digital meter. Get quick recognition and precise functionality for the easiest to use and easiest to read panel meter available.
Easy-to-Read Display Technology
The APM Micro Meter’s display combines the best of both digital and analog amp meters, making it easy to read even in challenging conditions.
- Adjustable Brightness: Change the backlight brightness to suit different environments.
- Two Contrast Options: Order the positive display for bright sunlight, or the high-contrast negative display for indoors.
- 40-Segment Curved Bar Graph: Get an immediate visual indication of parameters.
- Wide Viewing Angle: Operators can read the meter from a range of positions.
- Large Readout: The APM Micro Meter features four 12mm [0.47″] digits for clear and accurate readings.
User Configurable Micro Ammeter
The APM Micro Meter is highly configurable using the APM configuration software. The easy-to-use, free software allows you to tailor the meter to your specific needs.
- Color Changing Backlight: Configure color and intensity, with flashing or static alerts for specific conditions.
- Configurable Scale & Range: Adjust offset, gain, linear scale, and min/max range with 20-point non-linear scaling.
- 10 Independent Alarms: Set conditions and actions to meet your requirements.
- 16 Pre-set Configurations: Use position switches on the back of the meter to select pre-set standard configurations without software.
- Messaging Area: Display custom messages and annunciators.
- Digital Output Delays: Set delays from 0.5 to 120 seconds.
Remote Monitoring
Every APM comes with a free lifetime subscription to Trumeter Cloud so you can remotely monitor the status of your systems. Just add on our plug-and-play APM Gateway to get:
- Customizable alarm conditions and thresholds for notifications
- Unlimited email notifications, plus options to add instant text messages
- Exportable data stored securely in the Cloud
Output & Communications
The APM Micro Meter comes standard with two outputs to communicate with other systems: 1 digital (open collector) or 1 analog (4-20mA). In certain circumstances we can customize the APM Process Micro with Modbus RTU for further communications.
