Greisinger

Greisinger is a leading German manufacturer of precision measuring instruments for temperature, humidity, pressure, flow, oxygen, CO2, and other measured quantities for industrial and laboratory applications. The company Greisinger Electronic GmbH, based in Regenstauf near Regensburg, develops and produces a complete range of handheld measuring instruments, data loggers, fixed transmitters, and associated sensors for demanding measuring environments.

The most well-known product program of Greisinger includes the GMH series digital handheld measuring instruments widely used for temperature measurement, pressure monitoring, and air humidity measurement in industry, laboratory, and installation work. The GMH-3000 series includes thermometers for K-type thermocouple sensors, J-type sensors, and PT100 RTD sensors with measurement accuracy up to 0.1°C. The GMH series pressure meters measure absolute pressure, gauge pressure, and differential pressure in ranges from -1 bar to more than 400 bar depending on the chosen type.

For gas analysis, Greisinger supplies the GOO series oxygen meters measuring oxygen concentration in gas phases, and the GCO2 series CO2 meters for air quality monitoring and process control in fermentation and packaging applications. The GFPM series flow meters measure the flow volume of liquids via the magnetically inductive measurement method, while the GDUSB data loggers feature USB connection for direct PC connectivity.

Greisinger also supplies industrial transmitters with 4-20 mA output for temperature, pressure, and humidity that can be integrated into PLC systems and SCADA environments. The transmitters are available with ATEX certification for explosive atmospheres in zone 1 and zone 2. DAkkS calibration certificates are available for all Greisinger measuring instruments requiring traceability to national measurement standards.

At Verkopershulp.nl you will find a comprehensive range of Greisinger measuring instruments, sensors, calibration cables, and associated accessories. Our measurement technology specialists advise on the correct instrument choice based on your measured quantity, desired measuring range, accuracy class, and environmental conditions.

History

Greisinger Electronic GmbH was founded in Regenstauf, Germany, as a manufacturer of electronic measuring instruments for industry and scientific research. The company built its market position by consistently supplying accurate, reliable, and user-friendly measuring instruments that respond to practical needs in the manufacturing industry, laboratory, and installation technology. Greisinger progressively expanded the product program from basic thermometers to a complete measuring instrument program for all relevant process quantities. The company today exports measuring instruments to customers in more than 80 countries and cooperates with accredited calibration laboratories for DAkkS calibration certificates that are internationally recognized.

Frequently Asked Questions

What is the difference between K-type and PT100 temperature sensors with Greisinger? ▾
K-type thermocouples (NiCr-Ni) are suitable for temperature measurements from -200°C to +1350°C and are robust and cost-effective. However, they are less accurate (typically ±1-2°C) than PT100 RTD sensors. PT100 sensors measure in the range from -200°C to +850°C with higher accuracy (typically ±0.3°C or better) and better long-term stability. For climate and laboratory applications requiring high accuracy, PT100 is preferred. For high-temperature applications above 400°C, the K-type thermocouple is the correct choice.
How do I connect a Greisinger GDUSB data logger to my PC? ▾
Connect the GDUSB data logger via the supplied USB cable to your PC. Install the free GSOFT3050 software from the Greisinger website. The software automatically recognizes the logger via USB. You can set the log interval from 1 second to 24 hours, read out measurement data, display graphs, and export measurement data to Excel or CSV. For multiple loggers you can connect and read multiple units simultaneously.
Which Greisinger instrument do I use for differential pressure measurements? ▾
Greisinger supplies the GMH-3161 and GMH-3100 series differential pressure meters for measuring the pressure difference between two measurement points. Ranges vary from 0-100 Pa (for filter monitoring HVAC) to 0-600 mbar and higher. For fixed installation, differential pressure transmitters with 4-20 mA output are also available. The choice of measuring range depends on the expected pressure difference and the desired resolution.
Are Greisinger measuring instruments supplied with a DAkkS calibration certificate? ▾
Yes, Greisinger supplies measuring instruments with a factory calibration as standard. A DAkkS calibration certificate with traceability to national measurement standards can be ordered additionally at instrument delivery or subsequently via a certified calibration laboratory. Verkopershulp.nl can inform you about the availability of DAkkS calibration per instrument type and the required delivery time.
Which Greisinger instruments are available with ATEX certification? ▾
Greisinger supplies a selection of temperature transmitters, pressure transmitters, and humidity sensors in ATEX configuration for zone 1 (II 1 G Ex ia IIC) and zone 2 (II 3 G Ex nA IIC). The ATEX-certified models are suitable for use in explosive atmospheres with flammable gases and vapors. Consult the product catalog or contact our specialists for the available ATEX models per measured quantity.
What is the delivery time of Greisinger measuring instruments? ▾
Common Greisinger handheld instruments, such as GMH series thermometers and pressure meters, are typically available from stock at Verkopershulp.nl with delivery within 1-3 working days. Special versions, sensors with special housings, and ATEX-certified instruments may have a delivery time of 1-3 weeks. Data loggers and transmitters are generally available within 1-2 weeks. Contact us for current stock and delivery times.
Can I integrate Greisinger transmitters into my PLC or SCADA system? ▾
Yes, Greisinger industrial transmitters are available with a standardized 4-20 mA output that connects directly to the analog inputs of common PLC systems (Siemens, Allen-Bradley, Beckhoff, etc.) and SCADA platforms. Certain Greisinger transmitters are also available with Modbus RTU interface for direct digital communication. Specify your desired communication protocol when ordering for the correct version.
Are Greisinger PT100 probes available in stainless steel for liquid measurements? ▾
Yes, Greisinger supplies PT100 immersion probes in stainless steel 316L with various insertion depths and connection heads for direct liquid temperature measurement. The probes are available with connection head type A (DIN B) or with direct cable connection for linking to GMH series handheld instruments or industrial transmitters. The protection tube diameter varies from 4 mm (minimal insertion opening) to 8 mm for standard thermowell connection.
