FOTEMP-H2 Handheld Signal Conditioner

FOTEMOP-H2 Handheld


Single and Two Channel Portable Signal Conditioner

IMPORTANT NOTICE: Effective April, 2022, the FOTEMP1-H single-channel handheld signal conditioner has been discontinued and will be replaced in 4Q2023 with the new model FOTEMP-H2 series. 

The new FOTEMP-H2 series offers unique flexibility with choice of 1 or 2 optical ports. The Lithium-Ion battery provides portable life up to 16 hours. The unit can be charged via supplied 12VDC wall charger or USB-C connection.  Battery operated for maximum flexibility, the FOTEMP-H2 can remotely log data and store on an accessible microSD card for later retrievable.

The FOTEMP-H2 features a large bright Color LCD  display with backlight and USB-C communication port for real-time data acquisition. It can be controlled directly using the front-panel keypad or the supplied “FOTEMP-Assistant” data logging software. One LED indicates battery charging status while second LED displays sensor status.

The TS series temperature sensors are completely passive, non-conductive, and thus immune to EMI, RFI, microwaves, high voltage, and ground loops. Ideal for making temperature measurements in high electromagnetic field environments such as MRI, in microwave fields and other environments, where measurement with RTDs, thermocouples, and electronic-based temperature sensors is not possible.

Resolution 0.1 °K
Channel sampling rate 4 Hz (1 channel) or 2 Hz (2 channels), 250ms per active channel
Communications USB-C
Data logging Continuous or timed temperature internal logging via microSD card, spectrum snapshots. Also supplied with FOTEMP-Assistant data logging software for PC-controlled data logging and changing internal parameters.
Display 3.5″ Color LCD
Optical interface ST, compatible with all TS series fiber optic temperature probes
Temperature Storage: —20°C to +70°C
Operating: 0°C to +60°C
Dimensions/Weight/IP 120 x 112 x 40mm, 0.6kg, IP54
Materials Aluminium, Metallic
Warranty 2 years
Calibration Options Option A1= -20°C to +150°
Standard A2= -40°C to +200°C
Option B= -40°C to +300°
Option C= -200°C to +300°C
Calibration Intervals Under normal use, the instrument does not require recalibration. When sensors and cables are changed, a One-Point Calibration is required. Recommended cal interval is 24 months for ISO systems.
