Since many years Gealog components are used at spring monitoring stations. The standard sensor configuration is discharge (water level), water temperature, conductivity and turbidity. Please send your requirements. We will configure an optimal measuring station for your particular application.
Logotronic - Gealog Automatic Weather Stations

Automatic Weather Stations composed of the various components of the Logotronic range of products. Especially the Gealog SG datalogger is perfectly suited for synoptic or climatological measuring networks due to his high processing power. For lower requirements i.g. for precipitation stations, also the Gealog ftp module can be used.
Hydrometric Stations

Since 30 years Logotronic is supplying hydrometric stations for rivers, lakes and for groundwater. Based on the flexibility of the measuring equipment different sensor technologies can be used, like - Pressure sensor - Radar water level sensor - Acoustic Doppler Profiler (ADP) - Shaft encoder Please send your requirements. We will configure an optimal measuring station for your particular application.
Water quality monitoring station

We supply automatic stations, equipped with: - Single sensors for high accuracy measurements (i.e. water conductivity) - Multiparameter probes for the measuring parameters conductivity, pH, ORB, Turbidity, dissolved Oxigen, algae - Measuring station combined with automatic water sampler Please send your requirements. We will configure an optimal measuring station for your particular application.

Products by SPOHR-Messtechnik GmbH

Spohr Products
Spohr - Water Level Meters

SPOHR Water Level Meters are designed for fast, easy and reliable measurements of water levels in wells, bore holes, observation tubes, tanks and surface waters, etc.
Spohr - Water Level and Temperature Meter

For measuring water level and water temperature in wells, boreholes, levels, containers and water bodies.
Spohr - Tag Line Devices

The SPOHR tag line serves to gauge the total depth of the firm substrate of boreholes, observation wells and open water bodies.
Spohr - Staff Gauges

SPOHR staff gauges are produced from fire-enamelled sheet-Steel. This design is paticulary well suited for unprotected use in water and outdoors, because almost no dirt can remain adhered to the completely smooth surface and suberb corrosion protection is guaranteed. Furthermore the colors and surface are extremely resistant to weathering influences and solar radiation. The enamelled staff gauges are drinking water-safe, although they can also be used...
Spohr - Water Level Measuring Set with Well Whistle

The complete water level measuring set consists of a well pipe and a tape measure in a special frame with support. The tape measure is connected to the well whistle probe with triple spring end, chain and snap hook.
Spohr Monitoring Well Caps
Spohr - Aluminium Wee Sealing Caps

Aluminium wee sealing caps with hexagonal standard closure or pentagonal safety closure. For protecting ground water observation and monitoring wells. The material selected for the sealing caps is a particularly tough special alloy and is weatherproof, frost-proof and corrosion resistant.
Spohr - Round Plastic Sealing Caps

The round sealing cap is ideal for flush mount wells, because the pipes can be cut to the correct height and no adaptor is required for the well cap. An additional advantage is that locking takes place centrally from above, and this means that no space issues arise when opening and closing. Fastening takes place using a clamping ring.
Spohr - Artesian Well Sealing Caps

Press ring closed with overlaying flange and ball valve. Against water pressure up to 3 bar. Available diameters 2' – 12'. metal parts and screws made from VA. Press ring made from EPDEM. Ball valve from forging brass. 1' ball valve with 3' – 12' caps. ¾' ball valve with 2' caps.
Groundwater Samplers
Spohr - Model 407 - Stainless Steel Bladder Pump

Stainless steel Model 407 Bladder Pumps provide consistent, accurate, reliable groundwater samples in all applications. Ensuring no air/water contact during operation, pumps are ideal for VOC sampling. PTFE bladders are ideal for dedication. Inexpensive polyethylene bladders are also available. Stainless steel pumps are effective at any angle, to depths of 500 ft (150 m), and are ideal for low flow sampling.
