Engineering heritage of Greisinger in Regenstauf and integration into Senseca

The German instrumentation manufacturer Greisinger electronic GmbH was established in 1980 in Regenstauf, Bavaria.

Over four decades, the Regenstauf facility developed a strong reputation for designing durable, fast-responding portable measuring instruments, interchangeable probes, and industrial transmitters for laboratory diagnostics, HVAC engineering, energy auditing, and food processing.

During the strategic consolidation of specialized European measurement brands, Greisinger operated as a core pillar of the GHM Group (GHM Messtechnik GmbH) before uniting under the global Senseca Germany GmbH umbrella in 2024.

Today, the Regenstauf competence center continues manufacturing the signature GMH, ECO, PRO, and G handheld series alongside precision temperature and pressure probes.

Design and metrology of handheld digital thermometers ECO 120, ECO 121, and GMH

Portable digital thermometers Greisinger series ECO 120, ECO 121, and ECO 122 are engineered for demanding field and industrial temperature measurements.

The instruments pair high-accuracy platinum resistance sensors (Pt1000) with factory-linearized electronics, maintaining low measurement drift across wide operating spans from -200.0 to +450.0 °C.

For food safety inspections, catering workflows, and pharmaceutical checks, the waterproof ECO 121 series integrates fixed needle penetration probes in 1.5 mm and 3 mm diameters that achieve rapid thermal response times (t90 under 2 to 3 seconds).

Ergonomic ABS enclosures sealed to IP65 and IP67 protect internal circuitry against washdown environments and dust.

Precision manometers GMH 31xx/51xx and digital pressure sensors GMSD/MSD

For commissioning pneumatic control loops, cleanroom pressure cascades, burner manifolds, and hydraulic machinery, Greisinger manufactures the GMH 316x/8x, GMH 31xx, and waterproof GMH 51xx handheld manometer families.

Models with internal sensors measure fine differential pressures starting from 500.0 Pa, while external sensor models cover ranges up to 1000 bar.

Interchangeable digital pressure transducers from the GMSD series (for air and non-aggressive gases) and stainless-steel MSD series (for liquids and aggressive media) feature an integrated calibration memory chip.

Connecting a probe to a GMH 31xx/51xx indicator or GDUSB 1000 USB adapter automatically loads scaling parameters and supports high-speed sampling up to 1000 readings per second.

Indoor climate, dew point, and air velocity meters GMH 33xx and PRO D0x

HVAC commissioning engineers, building physicists, and industrial hygienists rely on Greisinger thermo-hygrometers series GMH 33xx, GFTB/GFTH, and the modular PRO D0x handheld platform.

Combined TFS humidity-temperature probes integrate a fast capacitive polymer humidity element with a Pt1000 temperature sensor inside a protective probe head.

The onboard microprocessor of the GMH 33xx computes dew point temperature, wet-bulb temperature, absolute humidity, and enthalpy in real time while accepting a secondary Type K thermocouple input for surface temperature delta checks and STS vane probes for air flow velocity measurement inside ventilation ducts.

Portable water quality analyzers PRO 51x, PRO 52x, and PRO 595

The Greisinger portable electrochemical water analysis portfolio encompasses dedicated pH/ORP meters (PRO 51x), conductivity meters (PRO 52x), and multiparameter analyzers (PRO 595).

Each handheld unit features an IP67 waterproof housing, backlit dot-matrix graphic display, and either standard BNC electrode connectors or M12 digital sockets for DX smart sensors.

Four-pole graphite and epoxy conductivity cells used on the PRO 52x series resist electrode polarization and fouling across wide conductivity ranges, enabling accurate determination of resistivity, salinity, and total dissolved solids (TDS).

Data-logging variants (PRO 515, PRO 525, PRO 595) record up to one million timestamped datasets downloadable via USB-C.

Wood and building material moisture testing with GMH 38xx and GMK meters

For timber kilns, woodworking plants, and building structural inspections, the Regenstauf plant produces both resistive and capacitive material moisture instruments.

Resistive meters of the GMH 38xx family paired with SET38 needle electrode kits store 494 material characteristic curves for timber species, screed, concrete, and plaster, applying automatic temperature compensation via a GTF 38 probe.

When finished surfaces must remain intact without pin holes, inspectors deploy non-destructive capacitive moisture meters GMI15-Plus, GMK100, and GMK210.

High-frequency dielectric field sensing at selectable 10 mm and 25 mm penetration depths locates hidden dampness pockets in concrete slabs, parquet flooring, thermal insulation, and fiberglass boat hulls.
