Micro Observatory

The new AIS Web Micro Observatory was designed to collect accurate and precise measurements from a variety of sensors.  This ability allows the user to put together whatever sensors that are required to monitor any environment. 

IMGP9406

The latest AIS Web Micro Observatory is a cutting edge patent pending instrument capable of collecting data from potentiometric, amperometric, conductivity, photo, thermocouples, RTD's, and any type of  sensors.  The instrument can do this in any combination of 25 sensors in all.  Since the instrument is a network based system the instrument can be easily multiplexed with a simple network hub.

The instrument has optional wireless capability and can be used to communicate longer distances with our radio systems.


The instrument has the following sensor inputs from the front panel: 

9 High Impedance Electrometers

3 Conductivity Meters

3 Photo-Current Meters

3 K-Type Thermocouple Amplifiers

The instruments' rear panel has:

7 Low or High Impedance Auxiliary Electrometers can be configured as needed.

Instruments are available for laboratory use and field.  Field instruments can come in a variety of configurations for the any environment.
