Project : RF Probe
The RF Probe is an instrument which measures complex impedances. The unit consists of a probe body on the end of which is mounted an enclosure housing the electronics.The probe provides simultaneous measurements of massecuite series resistance and series capacitance which are available as two separate 4-20 milliamp output signals. These signals may be used individually or in combination for control depending on the application.
For example, on beet massecuites, the series resistance signal correlates closely to massecuite brix, whereas the series capacitance signal is influenced more by mother liquor brix. For improved control of continuous pans, a signal highly biased towards crystal content may be derived by linear combination of the two signals in a predetermined ratio. The method of measurement and the use of the two signals to derive an optimum signal for control is patented and makes the RF Probe superior to other R.F. probes which only provide a single output.The DUOTRAC probe is designed to be used in processes operating at constant temperature. All of
the standard applications for which the probe is supplied are absolute pressure controlled or
temperature controlled. Should the probe be used in a non-standard application where such control is
not in place it should be noted that, as with any instrument measuring electrical properties of
solutions, the output of the probe will be affected by temperature changes.For control of cane sugar refinery white pans where ash is low, the series capacitance signal gives
good results. This signal provides a measure of liquor brix at the beginning of the boil which can be
used to establish seeding point. Also this signal responds to crystal content during the boil and can
also be used to control boiling up of the pan to strike.The instrument can also be used for brix measurement and control on various liquors.

Project : ION Charge Analyser
The ION CHARGE ANALYSER is a sophisticated instrument designed to monitor and control the chemistry of water particulate suspensions by measuring the surface charge of suspended particles. Here’s a detailed breakdown of its features, functionality, and applications:Measurement Principle:
The instrument uses the streaming current technique to determine the surface charge of suspended particles.
A current is generated due to the potential induced between two electrodes as charged particles move past them.

Project : Surfboard SharK Repeller
Surfboard shark repeller for surfboards, current version is factory fitted with optional electronics and batteries in separate sealed circular units that screw into the surfboard for easy removal and replacement with blank units in the event of the repeller not being needed. Future version will be stick on unit for easy retrofit to any surfboard.
PROPOSED PRICE
