Measuring equipment, such as a portable pH meter system, can include a plurality of probes for measuring different properties of a sample with each of the probes contacting the sample simultaneously. A reference source line connected to an appropriate reference source can be connected to each probe, while a signal line connected to each probe can provide a measurement signal. A switch assembly is provided for each of the probes in order to isolate the respective probes from each other to prevent any interference when measuring the sample.

A remote monitoring system for instrumentation that is capable of measuring certain characteristics of a process such as a pH value includes an instrument for providing a measurement output signal which can be stored. A comparison circuit can compare the output signal with a predetermined value. A transmitter can transmit when the output signal exceeds the predetermined value, and a receiver can receive the output signal and convert it into a measured result. The instrumentation can be pulled from the receiver and the output signals can be encoded to identify a particular instrument with distinct transmission time periods available in a plurality of transmitting channels.

Pretreatment apparatus and process for analysis of sugar, the apparatus including a mechanical work hand which moves a vial containing a sample to various stations where reagents are added to the vial and where other pretreatment processes are performed on the sample. The pretreatment apparatus automatically controls the movement of the vial from one station to another and the various processes performed at each station, the processes including removal and storage of the vial's cap, addition of reagents into the vial, centrifugation and heating of the sample, and evaporation of excess reagents.

A water measuring system for measuring different parameters of water having a compact configuration that can be easily calibrated is provided. A plurality of individual sensors, are mounted on the housing, including a dissolved oxygen measuring sensor that can be mounted at a position separate from the other sensors. A hood member can be mounted at the lower end of the housing member to protect the sensors. A container that is capable of holding a calibration liquid can be fitted onto the housing member to provide the liquid at a position that will only contact those sensors other than the oxygen measuring sensor during a single calibration procedure.
