Senseca, formerly the GHM Group, has launched the PRO 111 and PRO 115 handheld meter/data loggers for Pt100 four-wire probes, and also the PRO 131/PRO 135 data logger for thermocouple probes. These are redesigned with enhanced features.
“Due to the backlit dot matrix and clear text display, both of these devices now give a higher-quality LED screen, making the data more accessible. Data logging storage capacity is up to one million data fields. These high-precision instruments are suitable for temperature measurement across all industries. They are robust, reliable and ergonomically designed for both one-handed and benchtop use,” says Jan Grobler, managing director of Senseca South Africa.
The PRO 111/PRO 115 data loggers are high-class professional handheld meters for four-wire Pt100 probes. Any four-wire Pt100 standard probe can be connected, provided it is equipped with a M12 connector. It has a high-precision temperature-compensated analogue front-end meter that does not add any significant error in the measurement chain, which also features life chart viewing. The device incorporates sophisticated polynomial sensor linearisation to ensure best performance and to provide all relevant possibilities for calibration and adjustments.
The LED display offers a HOLD feature, which allows freezing of the measurement on display, while the REL feature shows the measurement against the measured value. The PRO 115 is easily connected via the USB C port for viewing or downloading files stored in the internal memory of the instrument, or for connection to the application software, Proxware.
Both models are dual-channel professional handheld meters for thermocouple probes. Any K, J, T, N, R, S, B and E standard thermocouple probe can be connected. They offer configurable surface correction factors, and can be set for use in combination with Senseca contact probes for enhanced measuring accuracy. The PRO 135 also has a data logging capability. They also offer HOLD and REL options. If two probes are connected, the instrument will calculate and show the difference between the measurement of the two channels.
Both the four-wire ropes and the thermocouple instruments offer acoustic alarms with high thresholds and optional hysteresis; statistical functions of Min, Avg and Max; IP67 waterproofing with a long battery life; external power via USB; and quick access to most used operations.
Grobler says that the redesign of the devices has enabled Senseca to improve functionality, accuracy and reliability, while still offering pinpoint-precision data logging to the highest of European standards.
