Gemini data loggers [uk] ltd offers waterproof probes. These waterproof probes are use with the tiny tag range of data loggers. The common cause of probe failure is moisture penetration, when water penetrates the joint where the cable enters the probe metalwork. The new tiny tag probes have been developed to incorporate a cleverly moulded handle ensuring a robust and watertight design. The result is a range of cost effective, watertight, robust probes suitable for applications as diverse as the tiny tag loggers themselves are. Other ranges probes includes, an end to the inherent problems of recording precise data in damp or even submerged conditions can be obtained.
