Humidified incubators offer warm temperatures with controlled additive humidity. Across the temperature range of 20-50°C, ±1°C at the sensor, these chambers can control relative humidity from set points of 50% through 80%. However, at 23°C it is possible to achieve 90% RH or more, while at 50°C, the RH can drop to as low as 30%. Control of RH uniformity depends on the RH generator used, which depends on the water source available. Both the Ultra Pure DI water type (±5% variation from RH set point) and the Tap Water type (±10% variation from RH set point) are available. Please specify at time of order placement. HIS33D is shown at right.

Humidified incubators have stainless steel interiors/exteriors and hinged glass doors, digital display of temperature/RH conditions and set points, temperature fail safes, four levels of epoxy coated wire shelves, fluorescent lamps, and casters. Applications such as concrete testing, ninhydrin curing, insect research, and vitamins/minerals shelf-life testing are examples of humidified incubators' many uses. Visit our ACCESSORIES list for options your application may require, such as an A/V alarm, chart recorder, solid doors, door lock, air ventilation port, water recirculation system, etc
