New SONODEPTH with microprocessor circuitry has features like LO DEPTH alarm. Compensations for water temperature, sweet or salt water selection, prnter port with graphic or digital printout at adjustable time intervals. It is an echosounder for measurng water depth in silting or sedimentation studies, dredging surveys in laes, rivers, ports, sea, etc. Operating on dry cells its probe is held over board touching the water surface, or mounted through the boat hull.

LOGICLIP : 16 Channel Logic Monitor Automatic selection of supply pins. High input impedance Wide voltage range This is a testing aid for electronic servicing, research and development, education, etc. It simultaneously monitors static and dynamic logic states of digital ICs of all types like TTL, CMOS, etc.
