Portable Instruments unite functionality with usability
The G 1000 series comprises compact and robust portable instruments that are used in a wide range of industries - from building services, industrial and appliance engineering to the food industry and aquaculture, as well as in laboratories and hospitals. The portable instruments are dust and water protected to IP65 and IP67 and feature high quality sensors.
For the water analysis the waterproof EC-meter, pH-meter, oximeter (G14xx/15xx/16xx series) are available, for the temperature measurement the G 1700 series with its universal thermometer and our new G 1200 thermocouple second thermometer are offered. Whereby the differential thermometer G 1202 allows the simultaneous use of 2 thermocouple sensors of type K and is therefore used wherever two temperatures have to be compared directly or monitored simultaneously.
The pressure gauges (relative and differential pressure), barometers and vacuum gauges (absolute pressure) of the G 11XX series ensure reliable results in terms of measurement resolution and accuracy at best price. The G 1690 oxygen measuring device is used for O2 analysis and measures the oxygen concentration in diving cylinders safely and reliably. The CO2 alarm monitor (G 1900 series) is especially known for its speed and accuracy and has a very wide measuring range up to 19999 ppm / 2 % CO2. Currently it is used for testing air hygiene (COVOD-19).
The EC-Meter G 1410 is a universal wide range conductivity meter for measurements of deionized water (cleaning processes, aquaristics). The EC-Meter G 1420 features a stainless steel ultrapure water measuring cell and is especially used for high resolution measurements of ultrapure water, alcohol, solvents and alike. The cost-optimized EC-Meter G 1409 with a measuring range up to 5000 µS/cm. is tailored to the needs of hydroponics and indoorfarming.
All instruments feature an ergonomic design and an illuminated display for excellent readability.

You can choose from various probes, electrodes and connectors as well as suitable accessories for your application. We offer the right solution to meet your requirements.
