INTRODUCTION
Thank you for purchasing OMEGA’s OS730K 30:1 Ultra Wide-Range IR Thermometer with “K”
Port. Please read this manual carefully and thoroughly before using the thermometer.
The OS730K measures surface temperature using either of two methods: non-contact (using
an IR thermometer with a laser pointer) or contact (using a “K” type thermocouple). A “K” type
bead thermocouple with a measurement range of -4° to 500°F (-20° to 260°C) is included in
the package. Non-contact measurements made by the IRT can be adjusted for the emissivity
of the surface, increasing the accuracy of readings.
The instrument automatically stores (records) up to 100 temperature readings in nonvolatile
memory for later recall. During a single scanning session, the OS730K simultaneously displays
real-time measurements on a primary (larger) readout and the maximum, minimum or
average measurement, or the largest difference between measurements, during that session
on a secondary (smaller) readout.
The OS730K, the “K” type bead thermocouple, a “9V” battery and this user’s manual are
packaged in a soft pouch inside a box.
