Connectivity is Easy with the EasyProbe
Connectivity is Easy with the EasyProbe The EasyProbe communicates using the underwater cable connected to the mantaMobile™. SD1-12 and MODBUS are available to connect to dataloggers, controllers, telemetry, and other third-party devices.
The mantaMobile is a rechargeable, high-capacity lithium battery with Bluetooth transceiver in a water-resistant case. The mantaMobile communicates via Bluetooth to Android or Apple display devices, including tablets and phones. The mantaMobile will power an EasyProbe for eight hours or
more.
MantaLink™ is the software app used to access the functions and data from your EasyProbe. Installing MantaLink on your display device takes just a few minutes. Connecting the EasyProbe to your display device takes just a few seconds.
Use MantaLink’s simple menu structure to perform basic functions like data capture, calibration, and sensor
parameter selection. The email feature allows quick transfer of field data to your home computer. Advanced features like geofencing make your sampling job even easier. With MantaLink’s black background and large, white letters, your data device is easily read in sunlight.

EasyProbe Specifications
Multiprobe specification charts often come with footnotes stating qualifications such as “accuracy specification good at the time and temperature of calibration” or “all values within 1 standard deviation” or “SC accuracy applies only at the calibration point”.
To avoid eyestrain from reading small print, the EasyProbe specification chart has “lab accuracy” and “field accuracy” columns. The latter gives you a more realistic idea of how your multiprobe performs, over time, under common field conditions.

Manta Trimeter Water Quality Probe
The Trimeter holds any one sensor* from the Sensor Parameters list, Plus temperature and depth sensors (both are optional). For example, a Trimeter configuration could be turbidity, temperature, and depth. Another example could be DO and temperature.
Water Level, Temperature & Conductivity Datalogging
The Levelogger 5 LTC measures and logs water level fluctuations, temperature and conductivity. It is programmed to record at intervals as often as 2 seconds. It includes an 8-year battery, memory for 100,000 sets of readings, and comes in 6 pressure ranges. A PFAS-free coating (inside and out) provides superior corrosion and abrasion resistance.
TLC Meter – Measure Accurate Temperature, Level & Conductivity
A TLC Meter provides accurate, stable temperature and conductivity measurements, displayed on a convenient LCD display for easy reading. Static water level and depth of readings are read off Solinst flat tape, which is precisely laser-marked every mm or 1/100 ft. Tape lengths are available to 300 m (1000 ft).
