Alta Labs environmental sensors are accurate and reliable! Control your processes and conserve energy. Put an end to "sick building syndrome" by improving indoor air quality!

TEMPERATURE

HUMIDITY

HD Series	Duct Mount Humidity Sensors 1%, 2%, 3%, 5% Accuracy Pendant, duct and insertion versions Non-polarity two-wire 4-20 mA...or 3-wire, 0-5 VDC/0-10VDC versions Thin-film polymer capacitive sensor element recovers from 100% saturation
HW Series	Wall Mount Humidity Sensors 1%, 2%, 3%, 5% Accuracy Monitor humidity and temperature with a single device - reduce installation cost Fully interchangeable RH sensor element - Calibration free Popular thermistor and RTD sensors available
HL Series	Wall Mount Humidity Sensors With LCD Display 1%, 2%, 3% Accuracy LED for local RH% indication RH/T model automatically toggles display between RH% and temperature indication Available with temperature transmitter, thermister, or RTD
HR Series	Recessed Humidity Sensors 2%, 3% Accuracy Looks great - "disappears" Installs fast - snaps into 1 3/8" hole
HO Series	Outside Humidity Sensors 2%, 3% Accuracy RH/T combination sensor for calculated dew-point Replace digital sensor quickly without calibration...maintain accuracy and eliminate downtime Recovers from 100% saturation...no damage to sensor
HT Series	Humidistat Designed for cost-effective direct control of humidifiers, dehumidifiers, valves, compressors, and other environmental control applications Wall and duct models - easy to install Direct control of electrical load - Form C relay output rated 1/8 HP
HX-485/ TX-485	Network Temperature and Relative Humidity Sensors Designed for use in HVAC and process control applications which require maintenance free operation Serial RS-485 output - improved signal integrity over conventional analog outputs, Modbus RTU

PRESSURE

PX Series	Differential Pressure Transducer - Dry Media Static pressure in duct or room applications Improved tolerance to overpressure and vibration reduce field failures Jumper selectable ranges reduce setup time and number of models to stock
PW Series	Differential Pressure Transducer - Wet Media Stainless steel media isolation Calibration free accuracy Jumper selectable ranges reduce setup time and number of models to stock
PH Series	High Pressure Transducer Compatible with freon, ammonia, and other 300 series stainless compatible liquids and gasses High accuracy digital sensor maintains calibration and reduces callbacks Lowest total installed cost

CARBON DIOXIDE

CX Series

CO2 Sensors Control HVAC in response to user needs - save up to 30% on energy by providing ventilation as required Microprocessor-based to reduce long-term drift and calibration requirements Optional relay output to trigger HVAC equipment at predetermined levels

CARBON MONOXIDE

GX Series

Carbon Monoxide Sensor Ventilation control in parking garages for energy savings Low-profile package mounts directly to conduit - no mounting hardware or concrete anchors required Microprocessor-controlled. High accuracy, excellent stability

WATER DETECTION

MX Series

Moisture Detector Protect vital computer and electrical equipment from water damage 10-year lithium battery and 24v powered models AC sensing prevents electrolysis
