LH-1.5-B
BenchtopRack and Stack
The LH-1.5 is a dynamic test chamber known for its ability to run unparalleled tight temperature and humidity control.
The test chamber is designed for minimal maintenance. Run long-term tests at a constant, steady-state temperature and humidity, or cycle testing with well-tuned reliability.
LH-1.5 model is a compact laboratory benchtop environmental test chamber. It's known for its exceptional ability to tune into and control temperature and humidity performance, within -20°C to +94°C (-4°F to +201.2°F) and 10% RH to 95% RH.
LH-1.5 test chambers feature heating systems equipped with open ceramic-core nichrome heaters for reliable and accurate temperature control within ±0.5°C.
The humidity system has a standard range between 10% RH and 95% RH. To extend your humidity range, see the optional features section. View RH Chart.
The cooling system in an LH-1.5 consists of a self-contained, compact, mechanical, single-stage refrigeration system.
The LH-1.5 can be fitted onto an optional floor stand to increase mobility and lab testing flexibility. A stackable floor stand allows for two chambers in the same footprint. You save valuable lab space, gain more test workspace, or can run independent tests concurrently.
LH Series Test Chambers have incorporated AESONE CONNECT instrumentation creating a robust connected device for a standard and uniform interface making operation easier. Learn more in the Instrumentation Tab below.

*Ideal ambient temperature conditions for test chambers is 23°C (73.4°F). The temperature and humidity range of assured performance is between 15°C and 25°C (59°F/77°F) and 30-50% relative humidity. Conditions outside this range may affect the performance of your test chamber and reduce the lifespan of the equipment.

Instrumentation
STANDARD INSTRUMENTATION
CONTROLLER 
LH Series Test Chambers have upgraded to include AESONE CONNECT creating a robust connected device for a standard and uniform interface making test chamber operation easier.
AESONE XCHANGE is hardware internal to the chamber that increases your functionality
- Connects the test chamber controller to your network for increased accessibility
- On-board multi-year data logging
AESONE SOFTWARE gives you the power to
- Remote chamber operation and monitoring,
- Web-based test profile creation,
- Viewing current data and historical data visually
- Secure multi-level user access
ADDITIONAL ONBOARD INSTRUMENTATION
WATLOW F4T PROGRAMMABLE CONTROLLER. Features a 4.3” capacitive touchscreen minimizing the chance for error. Ethernet communication supported by AESONE HARDWARE. View more controller options
SENSORS.
- TEMPERATURE SENSOR. Measured at the point of airflow entering the workspace. Class A, 3-wire, 100 Ohm Platinum RTD sensor
- RELATIVE HUMIDITY SENSOR. Measured at the point of airflow entering the workspace. Speed of airflow does not affect measurement. Sensor is highly accurate between 10-95% RH, over the entire temperature operating range of -70°C to +180°C (-94°F to +356°F)
- Solid-State Humidity Sensor
- View sensor options
OPTIONAL DATA LOGGERS. View additional data loggers
