Aquafog Temperature-Humidity Meter with Dew Point CP-301
The Aquafog Temperature-Humidity Meter with Dew Point CP-301 is a precision handheld thermo-hygrometer designed for accurate environmental monitoring in greenhouses, horticultural facilities, agricultural buildings, warehouses, manufacturing areas, and industrial humidification applications.
Unlike a basic temperature and humidity meter, the CP-301 also measures dew point temperature, giving operators a clearer understanding of moisture conditions and the risk of condensation within the environment.
With a broad 0–100% RH measurement range, temperature readings from -4 to 122°F / -20 to 50°C, a dual-readout LCD, and selectable °F or °C display, the CP-301 is especially useful for monitoring environments where Aquafog humidification and evaporative-cooling systems are operating.
Measures Temperature, Humidity and Dew Point
The CP-301 combines three important environmental measurements in one portable instrument:
- Ambient temperature
- Relative humidity
- Dew point temperature
Monitoring these conditions together provides a more complete picture of the environment than temperature or relative humidity alone.
Dew point is particularly useful in high-humidity applications because it indicates the temperature at which airborne moisture can begin condensing on surfaces.
This information can help operators better understand moisture conditions around:
- Plants and propagation areas
- Greenhouse structures
- Pipes and equipment
- Walls and ceilings
- Stored products
- Manufacturing materials
- Humidification systems
0–100% Relative Humidity Range
The Aquafog CP-301 measures relative humidity across an exceptionally broad range of:
This makes it especially suitable for environments where humidity may reach levels beyond the operating range of a standard handheld thermo-hygrometer.
Published humidity accuracy is approximately:
Because it can monitor humidity all the way to 100% RH, the CP-301 is a practical choice for demanding greenhouse, horticultural, agricultural, storage, and industrial environments.
Wide Temperature Measurement Range
The CP-301 measures ambient temperature from approximately:
Published temperature accuracy is approximately:
This broad range allows the meter to monitor many indoor agricultural, greenhouse, storage, manufacturing, and industrial environments.
Dew Point Monitoring
One of the key advantages of the CP-301 is its ability to measure dew point temperature.
Dew point monitoring can be particularly valuable when working with humidification systems because increasing relative humidity also reduces the difference between ambient temperature and the temperature at which condensation begins.
Monitoring dew point can help operators:
- Identify conditions approaching condensation
- Evaluate very humid environments
- Monitor moisture conditions around crops
- Check greenhouse climate conditions
- Protect moisture-sensitive materials
- Evaluate humidification performance
- Better understand temperature and humidity relationships
This makes the CP-301 especially useful in environments where precise moisture management is important.
Dual-Readout LCD Display
The CP-301 features a convenient dual-readout LCD display for quick environmental checks.
The display allows operators to monitor environmental readings directly from the handheld instrument without requiring permanently installed monitoring equipment.
Temperature readings can be displayed in:
This makes the CP-301 convenient for both Canadian and international applications.
Approximately 60-Second Response Time
The CP-301 has an approximate 60-second response time.
This allows the meter to stabilize and provide representative environmental readings when moved into a new measurement area.
For the most useful results, allow the meter sufficient time to acclimate to the conditions being measured before relying on the displayed values.
Portable Handheld Design
Because the CP-301 is a handheld meter rather than a permanently installed controller, it can easily be moved throughout a facility.
Operators can use one instrument to check conditions in:
- Different greenhouse zones
- Propagation rooms
- Growing areas
- Storage rooms
- Warehouses
- Production facilities
- Equipment areas
- Locations near fogging systems
- Areas where condensation may be a concern
This portability makes the CP-301 a useful troubleshooting and verification tool for larger facilities with multiple environmental zones.
Battery Powered
The Aquafog CP-301 operates using:
The batteries are included, allowing the meter to be used without connecting it to the facility’s electrical system.
Battery operation also makes the instrument convenient for mobile measurements throughout greenhouses, agricultural buildings, warehouses, and industrial facilities.
Used With / Compatible With
The Aquafog Temperature-Humidity Meter with Dew Point CP-301 is a standalone monitoring instrument and does not require an electrical or control connection to an Aquafog fogger.
It can be used alongside a wide range of Aquafog humidification, cooling, and environmental-control systems, including:
- Aquafog Turbo XE 2000 Fans
- Aquafog Turbo XE 2000-HS Fans
- Aquafog GT-500 Fans
- Aquafog GT 500-HS Fan
- Aquafog Hydro SS 700-DF Fan
- Aquafog Hydro SS 700-HS Fan
- Aquafog Hydro SS 700-BT Fan
- Aquafog XE-HRSM Mobile Fogging Machines
- Aquafog XE-CRSM Mobile Fogging Machines
- Aquafog XE-ORSM Odor Control Mister
- Other compatible Aquafog humidification and environmental-control installations
The CP-301 does not switch the fogger On or Off. Instead, it is used to measure and verify environmental conditions so operators can evaluate system performance and adjust their environmental controls as needed.
Useful With Aquafog Environmental Controls
The CP-301 can also be used as a monitoring and verification tool alongside Aquafog environmental controllers such as:
- Aquafog Digital Humidistat Controls
- Aquafog Mechanical Humidistats
- Aquafog Thermostat Controls
- Aquafog Timer Controls
- Aquafog Two-Stage Control
- Existing greenhouse automation systems
For example, an operator can compare the CP-301 reading with the setpoint of a humidistat or thermostat to help verify environmental conditions in a particular area.
CP-301 vs. CP-205
Aquafog also offers the CP-205 Temperature-Humidity Meter.
The CP-301 provides several important advantages for more demanding humidity applications.
CP-301
-
Humidity range: 0–100% RH
-
Temperature range: -4 to 122°F / -20 to 50°C
- Measures dew point
- Ideal for environments reaching very high relative humidity
CP-205
-
Humidity range: approximately 20–95% RH
-
Temperature range: approximately 32 to 122°F / 0 to 50°C
- Measures temperature and relative humidity
- Does not provide the same dew-point functionality
For applications where humidity may approach 100% RH or where condensation monitoring is important, the CP-301 is the more capable option.
