BA Series


Non-contact thermometer

All-in-one type


BA series

0 to 500℃


  • Scaling function
    The temperature range of analog output can be scaled within the temperature range as you like.
  • Built-in amplifier with compact body
    The first non-contact thermometer of its class incorporating a digital display, setting panel, and output function.
  • Emissivity teach function simplifies emissivity adjustment
  • Two-type optics
    Long focus : 30mm at 1000mm distance (BA30)
    Narrow focus : 6mm at 200mm distance (BA06)
  • Two-type analog outputs
    4-20mA type is suitable for long-distance transmission, and 1mV type is suitable for the connection with a panel meter.
  • The built-in coaxial laser marker allows you to sight measuring objects

Optical specifications






The optical resolution value stated above are at minimum 90% energy.
The size of measuring object should be sufficiently larger than the spot size.

  • built-in amplifier
  • coaxial laser marker
  • ε teach function
  • protection category: IP65
  • measuring range: 0 ~ 500 ºC
  • built-in digital display
  • analogue out-put


The first non-contact thermometer of its class incorporating a digital display, setting panel, and output function.


A built-in coaxial laser marker allows you easily to target a measuring object.


ε teach function simplifies emissivity adjustment

  1. measure temperature with any contact-type thermometer
  2. input the temperature value of (1)
  3. the unit automatically calculates the emissivity ratio and stores result in memory


long focus: BA30 type: Φ 30mm at 1000mm distance
narrow focus: BA06 type: Φ 6mm at 200mm distance

2 types analogue output

4-20mA of TA type: suitable for long-distance transmission

1mV/ºC of TV type: suitable for the connection with a panel meter
