The Artech Humidity Transmitter Model RX-01 is a compact two-wire transmitter with its capacitive sensor and electronic circuitry housed in a protective enclosure. The normal configuration is for wall mounting; a duct mounting configuration can be supplied on request. The transmitter is loop powered and controls the loop current at 4-20 mA according to the calibrated range.

Model RTX-01 is a combined Humidity & Temperature sensor which has in addition to the above an RTD sensor for temperature sensing, with an additional twowire output loop

The OXD-01 enables continuous monitoring of atmospheric oxygen levels. In confined rooms and work areas which have the possibility of reduced oxygen levels this can be of life saving importance. The monitor gives Alarm indication warnings at two levels:  1) An early warning when Oxygen falls below 20% signifies caution. 2) When the oxygen level falls below 19.5 %, a Danger alarm is activated so that appropriate action may be taken.  The alarm conditions are indicated by two LEDs with an additional beeper for the Danger level. The battery backup provided will last for a day in case of power failure.

Artech offers high performance low cost Indicators for Nitrogen levels from pure nitrogendown to atmospheric levels. These indicators are based on electro-chemical oxygencell sensors and can be used for nitrogen derived from air separation plants. A needle valve regulator and a flow indicator on the front panel enable the user to regulate sample gasflow to the recommendedrateof0.5litres/min.

The CP-04 wall-mounting Panel is an optional accessory. It houses the AUP-500L, Molten Steel Temperature Measuring System. It has the three Status Indication Lamps, Hooter and Thermocouple socket on the front panel. The panel is completely wired. The opening is from the front.

The Artech Humidity Indicator Model 210 RH directly indicates Relative Humidity. The Fully solid state circuit with no plug-in-cards enables the instrument to withstand severe vibrations and shocks.

This portable indicator is a convenient and handy instrument for field applications where a quick, easy and accurate measurement of nitrogen is required. The sensor being located within the instrument requires the gas sample to be delivered to the inlet port at a slight positive pressure. Alternately, a sampling pump can be provided. This indicator is based on electro-chemical oxygen cell and can be used for nitrogen derived from air separation plants. The instrument is microprocessor based and has a very readable white LED display. It is powered with a rechargeable battery.

APPLICATIONSCommon applications including checking of

• Nitrogen Purity
• For Cylinders
• For Air Separation Plants

The ARTECH FEM-01 Fuel Efficiency Monitor is designed to monitor performance of boilers, heaters, furnaces, etc. It measures Oxygen, Carbon Monoxide and Temperature of flue gas. From these values it computes Combustion Efficiency, Excess Air and Carbon Dioxide values. It is suitable for all gas, oil & solid fuels.

• Type : Pt /Pt-Rh-13 %, `R’ Type
• Type : Pt /Pt-Rh-10 %, `S’Type

The lamps indicate “READY”, “MEASUREMENT IN PROGESS” AND “MEASUREMENT OVER” , using the relay outputs of the Model AUP-500. These indications are of great help to the operator, as they indicate whether the thermocouple is properly inserted into the lance before taking a reading and also whether the reading was completed without thermocouple burn out; in case the thermocouple becomes open before the sampling process is complete “Measurement Over” will not be indicated.

The Remote Display Unit is a useful accessory which provides an easy to read numeric display of temperature recorded. The display numerals consists of LEDs assembled in an array to form 6 inch high characters. When a reading is taken, this unit receives serially pulsed data on a simple two wire connection. The Temperature is clearly displayed and if the unit is mounted at a suitable height, the reading can be visible to all on the shop floor.

The Artech microprocessor based Scan Indicator measures the temperature of several channels. It indicates on a digital display the channel being scanned at a regular interval of time, which is adjustable from 1 sec . to 99 secs per channel. The automatic scanning can be disabled by depressing the Manual (M) Key. Manual increment of the channels is possible by pressing the Up (↑) & Down (↓) arrow keys. The instrument accepts inputs from sensors through terminal strips situated on the back panel.

The Artech Scan Indicator conveniently measures the temperature of several channels. It indicates on a digital display the channel being scanned at a regular interval of time, which is adjustable from 1 sec.to approx. 30 secs.per channel.

The instrument accepts inputs from sensors through terminal strips situated on the back panel.

The Artech Digital Temperature Indicator provides a digital indication of temperature with a resolution of 10C or 0.10C. Thermocouple break protection and automatic cold junction compensation are added features of this instrument.

The Artech DPA10 is used for continuous measurement of the Dew Point of air and gases in Gas  Plants, Annealing Furnaces, Compressed Gases, Medical Gases, Natural Gas, Drying Systems  and Power Generation. The instrument is provided with a by-pass valve to isolate the sensor  when not in use, thereby ensuring fast response on re-startup. With the flow indicator the user  knows when the sample gas is flowing The regulator controls the pressure, thus preventing  damage of the sensor path by excess/fluctuating pressure.

The Artech Humidity Indicator Model 200 RH directly indicates Relative Humidity. The Fully solid state circuit with no plug-in-cards enables the instrument to withstand severe vibrations and shocks.

The Artech Humidity Controller Model 201 RH is a compact sturdy instrument useful for controlling the Humidity in enclosed rooms/chambers. The Set point adjustment is by means of a single ten-turn potentiometer. Depressing the “SET” switch displays the set Relative Humidity. In normal operation the display indicates actual Relative Humidity.
