In-Situ HERMIT SE 1000C Environmental Data Logger RS-232 4-20mA For Parts

In-Situ HERMIT SE 1000C Environmental Data Logger RS-232 4-20mA For Parts

The In-Situ HERMIT SE 1000C is a portable, self-contained environmental data logger designed for field measurement and recording of water-quality and environmental parameters. Housed in a rugged blue carry case with locking latches, it interfaces with In-Situ's standard transducers as well as most industry-standard 4-20 mA current-loop transducers through four locking yellow ports on the base of the unit. Recorded data can be viewed on the built-in LCD, printed via an optional field printer, or downloaded to a personal computer through the built-in RS-232C serial interface. This unit is being sold AS-IS for parts or repair due to a depleted on-board battery.

Applications

The In-Situ HERMIT SE 1000C was designed for environmental field monitoring — primarily groundwater quality assessment, surface water monitoring, and general environmental compliance work. Units like this were deployed at remediation sites, municipal water systems, industrial facilities, and environmental consulting projects where portable, battery-powered data logging was needed in remote or in-well locations. The 4-20 mA current-loop input made the logger compatible with a wide range of third-party transducers measuring parameters such as water level, pressure, temperature, conductivity, and pH, making it a versatile platform across environmental disciplines. The built-in RS-232C port allowed field technicians to offload logged data directly to a laptop for analysis and reporting. The HERMIT logger dates from the late 1980s to early 1990s era of portable environmental instrumentation, when non-volatile solid-state data storage was replacing paper chart recorders for field data collection. These units are still sought by technicians maintaining legacy monitoring installations and by environmental instrumentation collectors.
