BTM21A Controller for temperature with digital thermometer gun laser
When the working environment experiences a sudden change， the temperature measurement meter must be
placed in an environment for 30 minutes. The measurement can be resumed only when the temperature inside the meter is consistent with that outside it.
The electromagnetic field from electric welding and inductive heating must be minimized.
Don't put the temperature measurement meter close to or onto a hot object.
The meter must be kept clean so that dust is denied access to lens cone.
