SERVOTOUGH Oxy 1900 is a digital oxygen analyzer suitable for use in hazardous areas, with oxygen analysis standards set and a feature rich solution designed to meet the monitoring needs of the most challenging applications.
Product Description:
SERVOTOUGH Oxy 1900 is a digital oxygen analyzer suitable for use in hazardous areas, with oxygen analysis standards set and a feature rich solution designed to meet the monitoring needs of the most challenging applications.
The core of Oxy 1900 is Shifumei's patented paramagnetic oxygen sensor, which provides highly reliable, accurate, and stable oxygen percentage measurement. Using industry-leading patented paramagnetic technology to achieve stable, high reliability, and non consumable measurements - ensuring a longer lifespan and lower maintenance costs.
Technical parameters:
Gas to be tested: Oxygen (O2)
Sensing technology: paramagnetic
Performance:
◎ Measurement range: 0-25% O2 †
◎ Low detection limit:< ±50ppm O2
◎ Linear error: No significant error
◎ Repetitive accuracy:< 0.02% O2
◎ Accuracy (inherent error):< ± 0.05% O2 (± 95% confidence interval)
◎ Response time (T90):<6 seconds, under conditions of 200ml/minute and 1 liter/minute
◎ Zero drift (weekly):<0.05% O2/week
◎ Range drift (weekly):<0.05% O2/week
◎ Impact of sample gas discharge pressure: equipped with pressure compensation device: a 1% change in sample gas discharge pressure corresponds to a 1% change in reading
Not equipped with pressure compensation device: When the sample gas discharge pressure changes by 1%, the corresponding reading changes by 0.05%
◎ Sample gas pressure fluctuation: Flow changes of 50-250ml/minute (12-70 liters/hour, with built-in branch options) can cause zero point changes of<0.1% O2 and range changes of<0.5% reading
Signal output: standard configuration for each analyzer
◎ Analog output: 1 isolated 4-20mA/0-20mA output
◎ Analog output range: Users can choose the measurement range (minimum range 0-1% O2)
◎ Alarm: 2 potential free single pole double throw relays (30V DC 1A)
◎ Status signal: 4 potential free single pole double throw relays (30V dc 1A): Instrument malfunction, maintenance required, under repair, and mA range indication
◎ Digital communication: Modbus RTU (RS485) or Ethernet (Modbus TCP)
Work environment:
◎ Temperature: Operating temperature:- 10° … +55°C (+14°F … +131°F)

Physical parameters:
◎ Dimensions (W x H x D) 448mm (17.6 ") x 235mm (9.2") x 227mm (8.9 ")
Online dew point meters can accurately measure the dew point temperature of air or other gases. This series of dew point meters has the advantages of high accuracy, wide applicability, and low cost. They are suitable for steel, petrochemical, oven, drying oven, environmental testing, calibration laboratory, paint booth, process gas monitoring and gas production fields, using the principle of spotlight measurement to ensure high accuracy and reliability.
Due to different cooling methods and detection control methods, online dew point meters can be divided into multiple types. Its calibration uses a thermoelectric cooler to cool the dew point sensor, so that the water vapor in the sample gas condenses on the dew point sensor; The signal collected by the receiver is automatically controlled by a circuit to maintain equilibrium between the dew point on the dew point sensor and the water vapor in the gas. Accurately measure the temperature of the dew point sensor using a platinum resistance thermometer to obtain the dew point temperature of the gas.
A gas metering system is defined as a transfer in which a fluid or gas is measured and sold from one direction to another. In the process of trade handover, accuracy is crucial for both the company delivering the materials and the ultimate recipient when transmitting them. CTM is defined as an instrument designed, installed, and operated to meet the requirements of trade handover measurement. Trade handover requires a complete metering system designed and manufactured for measuring product gas applications, not just flow meters.

There are various measurement methods for online dew point meters, and their performance and price are completely different. This requires caution when choosing instruments, not only considering performance and price, but also the location and measurement of the instrument. So how to choose a suitable dew point meter for natural gas pipelines?
The measurement of dew point is very important for meteorology or other industries closely related to temperature. Usually, we accurately measure it through online dew point meters. In fact, there are many different classifications to meet the needs of different occasions.
Founded in March 2015, it is a company specializing in the gas analysis instrumentation industry and the field of high-precision sensors.
