Designed to deliver time and time again in even the harshest conditions, the TruBlue 555 LEVEL is battery powered and made with 316 stainless steel or titanium.  A fully sealed design and advanced, power-conserving microcomputer technology enables it to log level (depth) and temperature for up to five years. Since these units do not require onsite power or a programmable logic controller (PLC), a terminal box isn’t necessary. The TruBlue 555 vented level data logger is an excellent choice when reliability, accuracy and precision matter.
