SAIV TD301 / TD303

The TD301/TD303 are precision instruments measuring temperature and depth (pressure) in the sea, lakes, water reservoirs, groundwater, rivers and on R.O.V. etc. All settings like measuring interval, real time clock etc, are accessed via menu. The programmed settings and calibration coefficients are maintained in nonvolatile eeprom, and will not be changed/lost if power is disconnected.



The model TD301 has a built-in replaceable battery for self- contained recording applications. On/Off- switching is by a magnetic key or from keyboard.



The model TD303 is for on-line applications with external power supply and has an extra feature of 5Hz sampling with programable output formats to suit the host unit. Both units have a built-in data memory “ring memory” where the oldest data will be overwritten when memory is full. Data are recorded in physical units and simultaneously transmitted via an RS232 I/O watertight connector for on-line use.


Robustness and complete protection from leakage has been obtained by vacuum molding the electronic and all other components in solid polyurethane. A comprehensive PC-program is supplied with the units for easy communication, programming and presentation/processing of data. For remote readout and monitoring, the manufacturer offers several options: Communication Unit CU901, for two-way communication via Iridium satellite, GPRS with embedded web server, GSM and UHF/VHF
