Traceable Excursion-Trac™ Data Logging Thermometer with Calibration; 1 Bottle Probe

  • ...uration. The TL2-A is two thermometers in one instrument, with two channels allowing simultaneous temperature measurement in different locations. The TL2-A is well suited for establishing temperature traceability in equipment that requires high accuracy. The TL2-A is also perfect for metrology applications and as a calibration reference thermometer..
  • The TL2-A can be ordered with sensors included or the user can provide their own sensors. Sensor coefficients can be entered from a PC making it easy to change from a daily use RTD to a SPRT including user selectable choice of ITS-90 or Callandar-Van Dusen equations. Units come with 5 point resistance calibration from 20 to 425 ohms. With available PRT(s) ThermoProbe can provide a temperature reference system. Standard sensors are 100Ω wire-wound platinum RTDs in a stainless steel ¼” sheath 13.
  • The intuitive user interface allows easy configuration of temperature units, display resolution and a relay output. Minimum, maximum and average temperatures are automatically stored to memory for later reference. The interface allows viewing of Highest, Lowest and Average Readings, Zero Offset adjustment for sensor drift and readings in C, F, K and Ohms. The versatile data logging feature can be used to s....

GY-AS3935 Lighting Sensor Module SPI I2C MA5532-AE Lighting Strike Thunder Storm Distance Detector Breakout Board

  • Reference link: https://tinyurl(dot)com/AS3935-light-detector.
  • Video link: https://youtu(dot)be/oXqSIyaHR_I.
  • The splitter uses an inductor (antenna) designed specifically for this application, and the board is fully calibrated.This ensures that you can support low-level IC calibration without having to write a large back-end – focus on your end application!.
  • This sensor cannot drive an LCD display on it own It will need a microcontroller, like ESP8266/ESP32 or Arduino Pro Mini / Pro Micro 3.3V The Microcontroller will control the sensor and control the display as well..
  • What you will get is : 1 X GY-AS3935 Lightning Sensor.
