HI 3002 FOR IN-LINE INSTALLATION

The drawing illustrates the ideal installation system since the stream

pressure in the pipe forces the air bubbles out automatically.

HI 3001D illustrated preaviously can also be mounted in this fashion.

However the longer

stem of HI 3002 fa-

cilitates an easier

escape route for any

air bubbles. HI 3002

comes with external

1/2” NPT and

thread 60 mm (2.4”)

immersion level.

HI 7638 FOR IN-LINE INSTALLATION

HI 7638 comes with

stainless steel external

3/8” NPT thread and

60 mm (2.4”) immer-

sion level. It can work

at temperatures of up

to 120 °C and should

be used in high tem-

perature/pressure applications such as in boilers (HI 9923).

HI 3002 FOR TANK INSTALLATION

Due to its Ultem® and sealed body, HI 3002 can be installed

directly in a tank or vat without requiring a probe holder.
