Remote-Reading Magnetic-Back Thermometers with Calibration Certificate
Externally monitor the air temperature inside freezers, refrigerators, water baths, and incubators. These thermometers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. They have a probe with a 10-ft. cable that connects to a magnetic-back external display. The probe is insulated in a bottle filled with mercury-free fluid to prevent false readings from rapid temperature changes such as opening freezer doors.
The display simultaneously shows the high, low, and current temperatures. These thermometers have a programmable alarm to indicate when temperature rises above or below your actuation point.

Vibration-Monitoring Kits
Keep machinery running smoothly by monitoring its health and status from your computer. Often used with electric motors, pumps, and lathes, these kits measure changes in vibration and temperature—identifying equipment problems and potential failures before they occur. Plug in the sensor, set your thresholds, and view data directly on your screen. You’ll also receive email notifications when vibrations move beyond your specified range, making them good for preventative maintenance. These sensors are 20 times faster than our other vibration monitors, and they don’t require devices such as programmable logic controllers (PLCs) to operate.
Sensors mount directly to your equipment. Use the magnetic base for quick installation, or use the threaded hole for a more permanent setup. Once the sensor is hooked up, you can either wire it directly to the receiver or connect it to the wireless transmitter to view data remotely.
Kits with a USB connection link only to your computer for direct and easy monitoring.
Kits with an Ethernet connection can be configured to a wider network, transmit data over longer runs of cable, and integrate into other automated systems, such as a PLC.

Handheld Machine-Monitoring Sensors
and
Temperature
Monitor the health of pumps, engines, and other rotating equipment from your wireless device. These battery-powered sensors measure speed, acceleration, and temperature to help identify potential problems related to balance, alignment, and lubrication. Good for daily maintenance checks, they're battery powered and magnetic, so you can stick them on a machine, take a reading, and move to the next machine. They send readings using Bluetooth, which you can review in the field or offsite.
Install the app on your device and create profiles for multiple pieces of equipment—once created, you won’t have to enter information each time you want to do a maintenance check. Based on your machine profiles, the app will set default alarm thresholds. It will also recommend courses of action.
Sensors and replacement chargers cannot be sold to certain regions due to local energy efficiency regulations.
