The BA/HQF-B-C-1-C10-X is a BAPI-Stat Quantum combination room temperature and humidity sensor with a 10K-2 Thermistor temperature element and 0-10 VDC humidity output. The unit is equipped with a high-contrast LCD displaying temperature in °F and humidity in %RH. An on-unit slider provides occupant setpoint adjustment with a 50-90°F display range and 0-10V output to the controller. The capacitive polymer humidity element is factory-calibrated to ±2% RH at 25°C across the 20 to 80% RH range.
Best For
Occupied conference rooms, offices, and tenant spaces where occupants need to fine-tune comfort within BAS-defined limits, with full temperature and humidity feedback to the controller.
5-YEAR WARRANTY
Backed by BAPI's 5-Year Warranty. Factory-calibrated and tested to BAPI's quality standards before shipment.
Key Features
High-Contrast LCD
Upgraded display improves clarity at greater viewing distances, showing temperature, humidity, and occupancy status.
Capacitive Polymer Humidity Element
Long-term stable capacitive polymer sensor ±2% RH at 25°C across the 20 to 80% RH range, factory calibrated.
10K-2 Thermistor Temp Sensor
Passive 10K Type II Thermistor temperature element compatible with most BAS controller inputs.
Slider Setpoint Adjustment
Front-panel slider for occupant setpoint adjustment with 50-90°F display range and 0-10V output to controller.
Field Calibration
±5% RH field calibration adjustment in 0.1% increments via potentiometer (units without display) or programming pages (units with display).
Modern Quantum Enclosure
Clean modern ABS enclosure (UL94 V-0) mounts to standard 2"x4" junction box, European junction box, or directly to drywall (screws included).

Frequently Asked Questions
What is the humidity sensor accuracy?
±2% RH at 25°C (77°F) across the 20 to 80% RH range, using a capacitive polymer sensing element. Field calibration adjustment of ±5% RH in 0.1% increments is available.
What temperature sensor is included in the BA/HQF-B-C-1-C10-X?
This unit is configured with a 10K Type II Thermistor. The temperature sensor is passive (resistance output) and connects to terminals SEN1 and SEN2.
What does the display show?
The high-contrast LCD displays temperature in °F and relative humidity in %RH. Display options can be configured via programming pages including rotating, fixed major/minor, and single-value modes.
Can this sensor be field-calibrated?
Yes. Both temperature offset (P1) and humidity offset (P2) are set via the unit's programming pages in ±0.1° / ±0.1% RH increments. Enter Program Mode by setting DIP Switch S1 #1 (PAGES) to ON. A high-accuracy reference is recommended.
What mounting options are supported?
Standard 2"x4" junction box, drywall mount with included anchors, or European junction box (60mm mounting centers using the BA/HQ60 variants). Mounting screws are included.
