Testech LTE GSM Logger
PM035 – IP67 IP68 OEM Lower Power GSM LTE 4G GPS Remote Logger Telemetry with SDCARD flash Memory for Analog 4-20mA Digital and RS232C RS485 Modbus Instrumentation
Testech provide low power GSM Logger RTU Telemetry for monitoring of analog and digital water qualities, water level, flow, open channel flow, weather sensors, rain gauges and data center or control room sms alert remote monitoring applications. These logger are low power and can be power via a small SLA battery with solar panel, AC power or self powered. Other wireless interface can be added includes wifi bluetooth Loran RF for customized projects.
RS485 Modbus Sensor and Instrument can be interface by mapping to the IO for datalogging allowing the analog to be map to either the onboard 16bit ADC or External RS485 Modbus device such as Level Sensor, Flow Sensor, Water Qualities Sensors.
OEM and customization are welcome. Unit can be customized to user sensor, ip protocols and user can develop their own applications for OEM logger with firmware library provided. Unlike standard Linux base embedded boards these board are develop with embedded low power GSM and ultra low power micro controllers with onboard flash logger memory for robust field deployment and outdoor environment.
