Standard Probes (brass)
The Terminal & Securing Nuts are tightened to a specied torque during manufacture which causes the PTFE
Insulation to seal against the probe body. Therefore these nuts must not be adjusted because the seal will be
broken which may cause the probe to leak (see Figure. 1).
Angle Rajah ONLY must be used to connect wire to the probes because they clip directly to the Terminal Nut.
Spade Connectors must NOT be used because the Terminal Nut would require adjustment and therefore cause the
probe to leak (see Figure. 2).
N.B. The Probe Rod Grub Screw and Lock Nut are suitably tightened during manufacture, meaning the probe is
ready to be installed without any adjustment.
The ONLY instance a spanner should be used, is to turn the Probe Body in order to remove or reinstall the entire
probe.
IMPORTANT
Terminal and securing nuts must not be adjusted.
Only Angle Rajah are to be used to connect wire to the probes.

Probes are supplied in a standard length and should be cut to the length required, (the length of the probe being
replaced) ensuring measurements are taken from the underside of the probe hexagonal nut, remove any burrs
caused by cutting.
