We develop high-precision environmental instruments with a special focus on oceanographic research. Our product line includes high-precision pH sensors and low-power, high-stability spectrophotometric LED light sources. We also work on customized products for the customer's specific requirements. PRODUCTS: SP200-SM HIGH PRECISION IN SITU PH SENSOR: The SP200-SM is a high-precision colorimetric pH sensor designed for on-site operation in shallow water. SP200-SM pH sensors do not have significant drift, even after operating for several months. The sensor can be operated autonomously thanks to its internal Li-ion battery. HIGH PRECISION LABORATORY / IN THE IGNITION SYSTEM PH SENSOR: The SP101-LB is a robust and extremely stable pH sensor for ship and laboratory applications. Its construction guarantees accurate and stable measurements in all conditions. Thanks to its high measurement speed (20 measurements per minute), the system can be used for continuous flow measurements. The SL101-LB can be connected to an optional external conductivity/temperature sensor and can be thermostatized via two 1/2" barbed fittings. LIGHT SOURCES – SL001-SW (420-760 nm) compact LED, low power and fast settlement light source. The SL001 is a compact LED light source, low power, high stability and low amount of settling time. It features a modular construction, using user-replaceable LED modules, allowing for different wavelength configurations. With an extremely short heating time of 1 minute, it is possible to obtain stability below 0.25% at low impulse currents. Compared to traditional halogen light sources, the SL001 provides up to an order of magnitude lower power consumption with a virtually unlimited service life (> 10,000 hours) and does not require a fan. HIGH PRECISION UNDERWATER SPECTROPHOTOMETRIC SENSOR: The SP101-SM is a robust and extremely stable pH sensor for shallow waters, designed for oceanographic investigations. The design of the SP101-SM sensor allows to achieve the same precision that can be achieved in the laboratory, but it is deployed autonomously in the ocean, allowing long-term measurements without human intervention.
