The 1551A-20 is a thermometer from Fluke. Thermometers are a type of electronic test equipment used to collect information in a variety of applications. Professionals use thermometers to measure and document information during electrical troubleshooting,vehicle repair\/maintenance,HVAC applications and energy audits,science experiments,semiconductor technology manufacturing,and circuit terminal testing. Used and refurbished test equipment thermometers log data in Fahrenheit and Celsius and use an easy-to-read digital display screen. ValueTronics has thermocouple,infrared,dual K-type,non -contact,heavy duty,and other thermometers.","Additional Features:","The Fluke 1551A-20 \"Stik\" Thermometer is accurate,stable and durable,making it the best alternative to mercury thermometers and existing electronic thermometers. Intrinsically-safe,battery operated,portable reference thermometer designed to go where you work; whether working outdoors in environments where potentially explosive gases may be present or on the floor of a processing plant.","Thermometer probe and digital readout combined into one unit ","The stainless steel probe and digital readout are fixed together and calibrated as a system. The accuracy specification is easy to understand since it includes all uncertainty components,inc drift,for up to one year1. The large backlit LCD display rotates 90° degrees making it easy to read from any A user-configurable stability\/trend indicator lets you know when your temperature is stable enough to record an accurate measurement. A user-settable auto-off function extends typical battery life to three hundred hours . A low-battery indicator and stop-measure function prevent erroneous measurements from being made due to low battery life. A simple three-point calibration function allows you to easily and accurately calibrate the Stik Thermometer. Data logging to internal memory of up to 10,000 time-stamped measurements is optionally available.","Why calibrate process temperature sensors?","Because temperature greatly effects the accuracy of a volumetric measurement,process manufacturers of chemical,pharmaceutical,food or petroleum products require accurate temperature measurements—especially for processes where quality or custody transfer are regulated by government agencies. Since all temperature sensors are subject to drift with time,regular calibration or verification against a reliable reference thermometer is required. Finding a reference thermometer that is accurate,repeatable and robust,however,can be challenging.","What's wrong with my reference thermometer?","Industrial reference thermometers available on the market today,such as mercury-in-glass thermometers (or ASTM thermometers\") and portable electronic thermometers are useful,but both come with inherent problems. Although accurate and repeatable,mercury thermometers are fragile. The risk of a mercury spill poses potential hazards to the environment and to the health of personnel. Many of the United States and European Union countries have already banned their use in industrial applications. Some organizations have replaced their mercury thermometers with more durable portable electronic thermometers,only to discover that the RTD probes lack the repeatability and dependability required of a legitimate reference thermometer.","The best alternative to mercury thermometers","The Fluke Stik Thermometer is accurate,stable and durable,making it the best alternative to mercury thermometers and existing electronic thermometers. The thin-film RTD sensor incorporates the same characteristics of other premium reference thermometers designed by Hart Scientific,but it is more robust and less susceptible to drift. Accuracy and repeatability,however,are not sacrificed for improved durability.","Using a glass-stem mercury- or spirit-filled thermometer at different immersion depths,or at significantly different ambient temperatures from which it was calibrated,may require the application of emergent-stem corrections that can be tedious but necessary to calculate an accurate measurement. This isn't required with the Stik Thermometer. The sensor of the 1551A Ex requires a minimum immersion depth of only seven centimeters (2.8 inches),with no appreciable effect on the measured temperature due to heat loss through stem conduction. Some digital thermometers can become less accurate when used outside a narrow range of ambient temperatures. This isn't the case for the Stik Thermometer. Your measurement remains accurate in ambient temperatures from -10 degrees to 50 degrees celsius (14 degrees to 122 degrees fahrenheit). With a superior probe design combined with electronic functions that assist accurate measurement,the Stik Thermometer surpasses the capabilities of other digital thermometers and is the perfect substitute for your mercury thermometers.
