Leiderdorp Instruments

What Leiderdorp Instruments does

Leiderdorp Instruments BV, founded in 1987 and headquartered in Leiderdorp, Netherlands, designs, manufactures, and services proprietary monitoring instruments for geotechnical and hydrological applications. The company operates a single-site Dutch operation that handles product development (electronics, firmware, software), manufacturing, sales, service, and repair in-house, and it is a subsidiary of Hitma Groep B.V. within the Indutrade industrial group. Its portfolio centers on the ElliTrack family of IoT dataloggers (D+, D2, G, L, T, A, P, and the universal-input X), the standalone Bluetooth-enabled LevelStick groundwater logger, the Axilog III vibration meter, and a range of crack meters, EC sensors, and water-pressure meters, all of which feed into the cloud-based ElliTrack IoT portal for real-time monitoring, alarm notifications, and data export. More than 100,000 measurement locations have been deployed with the LevelStick alone, and the ElliTrack portal manages thousands of active measurement points per account.

The company sells primarily to Dutch government agencies (waterschappen, gemeenten, Rijkswaterstaat), drinking-water utilities (Brabant Water), engineering and geotechnical firms (Fugro, Avallo), and operators of critical infrastructure (Belgian energy-grid operators, chemical landfill operators). Revenue is generated through configured-to-order hardware sales, recurring ElliTrack portal subscriptions, service/maintenance/repair contracts, and turn-key measurement project delivery, with quote-based pricing under multi-year contracts and bundled hardware-plus-software offerings. Go-to-market is direct enterprise field sales with pre-sales consultation, supported by trade-show presence (Aqua Nederland), webinars, and a multilingual website launched in 2025 reflecting an ambition to expand beyond the Dutch market. The current strategic focus is the forced 2G-to-4G migration of an installed base of approximately 7,000 measurement points ahead of carrier shutdowns (Vodafone end-2026, KPN December 1, 2027), managed under a new Managing Director appointed in early 2025.

Revenue model

1. Hardware Product Sales: Sale of proprietary monitoring instruments including dataloggers (ElliTrack D/D+, D2, X, G, L), the LevelStick standalone logger, BLE Gateway, EC-sensors, crack meters, water pressure meters, and vibration meters. Products are sold with varying configurations (sensor types, measurement ranges, connectivity options). Hardware prices reflect specialized engineering for field use in geotechnical and hydrological monitoring.
2. IoT Software Platform (ElliTrack Portal): Subscription-style access to the ElliTrack cloud portal for data management, sensor monitoring, alarm notifications, and data export. The portal is required to fully utilize telematic data loggers. Pricing is bundled with hardware or offered as a separate service for ongoing monitoring projects.
3. Service, Maintenance, and Repair: Comprehensive support from initial contact through installation and maintenance. Includes calibration services, logger return and repair processing (with new RMA checklist system), spare parts, and technical support. The company has formalized its service process with pre-checks to determine repair eligibility.
4. Turn-key Measurement Projects: Custom turn-key monitoring project delivery combining hardware, software, installation, and ongoing support for specific client monitoring needs (e.g., dike monitoring, groundwater management, construction site monitoring).

Core offering

Leiderdorp Instruments BV develops, manufactures, and sells proprietary monitoring instruments (dataloggers, sensors, and crack/vibration meters) for geotechnical and hydrological field measurements. Its offering centers on the ElliTrack IoT portal, which manages sensor networks and provides real-time data, alarms, and exports, combined with a portfolio of telemetry-enabled and standalone Bluetooth-based loggers. The company also delivers turn-key measurement projects, calibration, and repair services.

Product overview

Leiderdorp Instruments provides geotechnical and hydrological monitoring solutions built around the ElliTrack IoT platform and its ecosystem of specialized dataloggers and sensors. The core offering consists of the ElliTrack web-based portal for managing sensor networks, complemented by telemetry dataloggers (ElliTrack D+ for boreholes, D2 for street pits, G for EC/conductivity, L for crack width, T for temperature, A for air quality, P for pulse counting, and X for universal 4-20mA/0-10V/SDI-12 sensors) and the standalone LevelStick Bluetooth-based groundwater logger. The LevelStick serves as an in-field readout solution without telemetry requirements, while the full telemetry loggers transmit via 4G, NB-IoT, or LoRa. A BLE-Gateway add-on bridges LevelSticks to remote monitoring. The Axilog III vibration meter serves construction monitoring separately. The company also offers turn-key measurement projects and product development services for third parties.
