Si preparations have already been shown to interfere with ISE determinations of ionized magnesium: Blood specimens obtained through tubing or syringes coated with silicone spuriously increased the concentration of ionized magnesium measured with an AVL 688-4 instrument, as documented by an increase in the
millivolt reading from the electrode [5].
A melt-pressure transducer measures pressure and gives a raw signal in
millivolt output.
For many years,
millivolt, or standing pilot heaters, were the only kinds of heaters available.
The LRX accepts a three-wire 100 ohm platinum RTD, K-type thermocouple, or direct
millivolt input.
Direct control of an ozonator with the Model 305 ensures a minimum ozone level, and
millivolt readout provides precise verification of ozone addition.
