Overview

The high reliability Manta+multi parameter instrument is manufactured for long-term use in outdoor environments, and many features of the instrument design are aimed at improving reliability and durability. For example, hidden sensors are better at avoiding damage to the sensors; The detachable cable interface can effectively protect the pins from bending or breaking; The LED of the host can display whether the circuit board is working properly.

Product Details

High reliability Manta+multi parameter instrument

It is manufactured for long-term use in outdoor environments, and many features of the instrument design are aimed at improving reliability and durability. For example, hidden sensors are better at avoiding damage to the sensors; The detachable cable interface can effectively protect the pins from bending or breaking; The LED of the host can display whether the circuit board is working properly.

Flexible on-site application

Multiple host models are available for selection and can be used for water quality measurement of freshwater, seawater, saltwater, and groundwater. It can be used for automatic recording of profiles, rapid on-site measurement, and is equipped with a waterproof Amphibian display recorder with handheld computer function. Manta comes standard with memory, and automatic recording can be achieved by simply adding a battery pack. To achieve online monitoring, we can provide wireless communication based on GPRS network or data acquisition devices with SDI-12 function. We have suitable solutions for your various requirements for monitoring tasks.

Simple and easy-to-use free software

We provide operating software with a Windows interface that enables settings, calibration, and data download functions. Real time data graphical display can help you intuitively obtain stable readings. The calibration log function will provide detailed calibration history records of the instrument. Supports Android and Apple operating systems, software can be installed and used through mobile phones or iPads
