The time-tested Multi Water Sampler technology reduced to the max – releasing a single water sampler at a precise depth

ABOUT

The Single Fire Module consists of a Plastic Water Sampler (also known as Niskin Bottle) of 1.7 litres capacity, mounted to a stainless steel rack which is equipped with a motor-driven release device. Power supply is made by internal rechargeable lithium-ion batteries, using the safest chemistry currently available.

DIGITAL STANDARD MODEL

The digital standard model, by design, is a stand-alone instrument. In online mode, operated in conjunction with standard electro-mechanical cables, the water sampler is actuated via push-button control by the battery powered Hand Unit. This also handles measuring data of the integrated high-precision pressure sensor.
In offline mode, operated in conjunction with steel or fiber ropes, the water sampler is automatically actuated according to a pre-programmed pressure (depth). Measuring data of the pressure sensor is recorded inside the internal data memory during the operation.

DIGITAL MODEL FOR CONTROL BY 
EXTERNAL CTD PROBES

This model has been designed to be controlled by external up-to-date CTD probes. It is equipped with a serial RS-232 port to receive action commands and provide a return signal to the CTD. This version is not equipped with a pressure sensor.

ANALOGUE MODEL FOR CONTROL 
BY EXTERNAL CTD PROBES

Even old-fashioned CTD probes are able to control the Single Fire Module. For this purpose a model with an analogue interface is available which is activated by a switched contact and delivers a return signal and battery voltage via two analogue channels. This version is not equipped with a pressure sensor.
