What Schaller Messtechnik GmbH does

Schaller Messtechnik GmbH is an Austrian privately held GmbH founded in 1995 by Maximilian Schaller and headquartered in St. Ruprecht an der Raab, Styria, where it operates a 14-person production, R&D, calibration-laboratory, and administration facility on a campus expanded in 2008 and again in 2019. The company designs and manufactures portable and online humidity and material moisture measurement instruments under the proprietary "humimeter" brand (an EU registered trademark since 2006), spanning capacitive and conductance-based handhelds, laboratory instruments, online transmitters (LF-TD series with RS232/USB/Ethernet/Profinet), and a LoRaWAN-based continuous monitoring system called huminode. Its flagship technology is a 2018 EU patent held by Max Schaller for ATRO-ton and water content determination in biomass, which underpins the market-leading humimeter BMA/BMA-2 platform.

The company monetizes hardware sales (humimeter series, FSA legally calibrated grain meter, huminode IoT sensors, LF-TD transmitters, 200+ accessories and professional scales), recurring software subscriptions via LogMemorizer PRO (cloud-enabled annual subscription with multi-device sync, user and tenant administration), and professional services that include an accredited in-house calibration laboratory (verification, adjustment, official Eichung via RWA for Austria), contract measurement services, and bespoke calibration curve development (Sonderkennlinien) for non-standard materials. Distribution combines direct e-commerce (schaller-meters.com), inside sales (Austria/Germany), regional field sales (named enterprise account managers covering Northern Europe, Africa, North America, Australia), and a worldwide network of trained channel and certified calibration partners (Romania, Croatia, Serbia, Slovakia).

Customers are spread across five verticals: agriculture, bioenergy and food processing (grain, biomass, hops, hemp, coffee, nuts, water activity for shelf life); construction and buildings (screed and concrete moisture via the KRL method as an alternative to the CM calcium-carbide test); paper and packaging (notable users include Mondi and Rondo Karton); climate and environmental monitoring; and industrial manufacturing (leather, textiles, pharmaceuticals, chemicals). Selected enterprise and institutional references include Mondi, KWB, Manner, Rondo Karton, Fernwärme Weiz, Saatbau Linz, Zotter Schokoladen, Alwera AG, TU Graz, and FH Campus 02. The company emphasizes "Made in Austria" quality, lifetime device support, and long-running academic partnerships with TU Graz, TU Wien, TU München, and HBLA Bruck an der Mur; leadership transitioned in 2021 to founder's stepson Bernhard Maunz and son-in-law Florian Postl as Managing Directors.

Revenue model

1. Moisture Measurement Hardware: Schaller Messtechnik's primary revenue stream is the sale of proprietary humidity and moisture measurement instruments. The product portfolio includes handheld devices (humimeter series), IoT sensors (huminode), laboratory analyzers (water activity), and online transmitters (LF-TD series). These are sold directly and through an international distribution network. Revenue is generated through one-time hardware purchases with a broad price range depending on device complexity and included sensors.
2. Software Subscriptions: LogMemorizer PRO is offered as an annual subscription with cloud connectivity, multi-device synchronization, and tenant management capabilities. This provides a recurring revenue stream tied to enterprise customers who need centralized data management. The Basic version is free and included with all humimeter devices.
3. Calibration and Certification Services: The company operates an in-house accredited calibration laboratory offering verification, calibration, and adjustment services for its own and third-party moisture meters. Additional services include official calibration (Eichung) of FSA grain moisture meters in partnership with RWA (Raiffeisen Ware Austria) for Austrian customers, and re-calibration in Romania, Croatia, Serbia, and Slovakia. Calibration is recommended every 2 years and generates recurring service revenue.
4. Accessories and Spare Parts: Schaller offers more than 200 accessory items including sensors, cables, calibration blocks, verification plates, sensor caps, replacement batteries, carrying cases, thermal printers, and precision scales. These are sold as add-on purchases to complement core device sales and generate repeat revenue from the existing customer base.
5. Contract Measurement Services (Auftragsmessungen): The company provides on-demand measurement services using its own calibrated equipment, including norm-compliant water content determination (e.g., drying oven method for biomass per EN ISO 18134-2). These services are targeted at customers who need occasional specialist measurements without purchasing equipment.
6. Custom Calibration Curve Development (Kennlinien-Erstellung): Schaller creates bespoke calibration curves for customers needing to measure non-standard materials. Using its accredited testing laboratory, the company develops and validates customer-specific calibration profiles that are then uploaded into the customer's device. This is a specialized, high-value service with custom pricing.
