Dissolved Oxygen :
Dissolved Oxygen Sensors for Dissolved Oxygen in Water.
Do you measure Dissolved Oxygen in
water or are you looking for replacement
dissolved oxygen sensors? A t
R.M.S Ltd we can supply replacement DO2 sensors that
are compatible with all modern instruments. All of our
electrochemical sensors can be supplied with or with out temperature
compensation. When it becomes necessary to change the membrane of
our Do probes, it is a simple task to unscrew the membrane cap, fill
a new one with the filling solution provided and screw on to the
probe. All we need is the make
and model of your DO meter so that we can determine the correct
connector etc - please
email,
phone or
fax us with your requirements and one of our team will contact you.
We offer two polyographic dissolved
oxygen sensors (types 601 and 602) and one galvanic dissolved oxygen
sensor model (type 603). These probes are designed for laboratory
dissolved oxygen measurements and have a standard 12mm body
diameter.
The galvanic probe (type 603) is
supplied as standard with the innovative new
Model 650 Dissolved Oxygen Probe Conditioner.
In air-saturated water (20.9%
Oxygen), type 601 has an output current of 600nA, type 602 an output
current of 60nA. The output of the galvanic electrode (type 603) at
saturation is 33 - 40mV.
Replacing the Teflon membrane is
quick and easy. Simply unscrew the old assembly, load the new one
with fill solution and screw it on to the electrode.
The residual output in zero oxygen
solutions for all of the electrodes is less than 1% of the output in
saturated water.
One or two A.T.C. sensors (Thermistor
or Pt100/1000) may be fitted to customers specific requirements.
The electrode is supplied complete
with 2 membrane assemblies and a 50ml bottle of filling solution.
A 50ml bottle of Zero Oxygen
solution is also available for calibration purposes.
When ordering replacement
electrodes please specify the Make and Type of instrument for which
the electrode is required.

B: Type of A.T.C. element (Th=Thermistor
or Pt=Platinum Resistance Element).
C: Resistance value of A.T.C.
D: Connector Type.
E.g. 601/2/Th10k/5pin DIN = Type
601 with 2m of cable, 10k Thermistor A.T.C. and a 5 pin DIN
connector.
