Organizations that need a low cost temperature and humidity data logging unit often consider the Dickson TP 125 Data Logger. This model is often used for refrigeration, clean room, and control room monitoring. This model has a temperature range that fits the previously mentioned applications. To determine if this data logger will fit your organization’s needs, consider the points below.
Range & Accuracy
The Dickson TP 125 data logger has the ability to measure temperatures -10°F to 176°F and the humidity range is 0 – 95% RH non-condensing. This range is comparable to other Dickson data loggers. The TP 125 uses an internal sensor to read temperature. Cable probes and thermocouples are available for this model. The temperature accuracy is ±8°F uncertainty from 0°F to 158°F. The humidity uncertainty is ±2% from 0 – 60%, ±3% from 61% – 95%.
The Dickson TP 125 data logger is a great option for organizations that may need to invest in multiple instruments at one time due to the low cost. At the time of this writing, new units can be purchased for $190 – $215. The Dickson TP 125 data logger calibration interval is between 6 – 12 months. The proprietary data logger software is not included with the unit.
Durability & Useful Life
One of the most important points to consider when buying equipment is cost versus usable life. This unit does not have a display or audible alarms, offered in other Dickson data logging models. The exterior is described as rugged. The compact size and battery power source allow for placement almost anywhere. This model comes with a 12 month manufacturer’s warranty that covers damage from normal use.
Many technicians note that the Dickson TP 125 data logger doesn’t get damaged easily from falls. These instruments are known for issues with reading accuracy over the long term. The ISO/IEC 17025 e2b calibration lab notes that 70% of these units fail annual calibration testing. If the unit has non-linear measurement inaccuracy, fixing the unit when making adjustments may prove difficult.
The bottom line is that the Dickson TP 125 data logger is versatile and affordable, with quality that reflects the price point.
