Scientific & Structured Monitoring
Monitor Multiple Heights
Monitor Multiple Locations
Monitor Delta-T
AUDIT-BUDDY offers a scientific and structured approach to monitoring, featuring a flexible design that allows the use of multiple sensors per stand to measure different heights and multiple locations, including across the front and back of racks or equipment (delta-T)
Step 1: Baseline Your Aisles
AUDIT-BUDDY QuickScan Mode
Static Temperature Map
AUDIT-BUDDY’s QuickScan Mode is designed for rapid assessments across multiple locations within your data center. This mode measures at various heights to create a comprehensive profile view of the environment. It helps in establishing baselines and quickly identifying problem areas such as hot or cold spots. With QuickScan, you can efficiently generate static maps of temperature, humidity, dew point, and more, providing essential insights for immediate action and optimization.
Check out the different types of static maps here.
Step 2: Collect Trend-Trend Information
Use the AUDIT-BUDDY LongScan Mode allows for detailed monitoring of a single location over a user-defined rate and time period. This mode is ideal for observing changes over time, creating time-trend graphs that providing a deeper understanding of environmental dynamics. By using multiple systems in LongScan Mode, you can create Dynamic Maps that offer a thorough analysis of your data center's performance. This mode is crucial for long-term planning and ensuring optimal conditions are maintained consistently.
Step 3: Evaluate the Cooling Efficiency
The ability of AUDIT-BUDDY to measure delta-T—whether at the rack, at the CRAC, or even on the roof—is crucial for diagnosing cooling efficiency. By providing detailed insights into temperature differences across various critical points, AUDIT-BUDDY helps identify inefficiencies and optimize cooling performance, ensuring the reliable operation of data centers and other temperature-sensitive environments.
What Type of Data Can I Generate?
Static Maps
A static map provides a snapshot of environmental conditions at a single moment in time, displaying data at multiple heights across various locations to reveal any variations.
Time-Trend Graphs
Trend sensor data at multiple heights over a period of time.
Server Delta-T
Evaluate the cooling efficiency at your server.
Reports
Auto-generate a comprehensive HTML report showing the scan details, data tables and images. This can be easily shared and viewed on any browser.
Uniformity Metric
Quickly evaluate how uniform (efficient) your area is.
Dynamic Maps
The Dynamic Map shows the change in conditions over a defined period of time using data from multiple systems in multiple locations.

FAQs
Is this just a data logger?
AUDIT-BUDDY records temperature and humidity data, but our stand construction and software are more advanced. While data loggers are individual sensors that need to be attached to physical device, the AUDIT-BUDDY is a freestanding monitoring tool, measuring at multiple heights. Our software takes and turns collected data into meaningful information so you don’t have to waste time on the data post-processing.
Do I need it if I have permanent sensors?
Even if you have permanent monitoring systems like BMS or DCIMs, AUDIT-BUDDY™ is an excellent tool for addressing gaps in coverage. It's ideal for measuring exhaust temperatures or double-checking the accuracy of your permanent sensors. AUDIT-BUDDY™ excels in transient monitoring applications, providing you with flexible and precise data collection when and where you need it most.
What is the sensing radius?
Place AUDIT-BUDDY™ as close as an inch away from the server rack using the carbon fiber rod or fix it directly to the surface using the magnetic plate. Purkay Labs recommends placing one TH1 Module near the floor, one TH1 Module close to the top of the rack and one TH1 Module in the middle of the cabinet to get a detailed stratification of the cabinet. We also offer a four sensor configuration to get even more stratification.
How long is the battery life?
AUDIT-BUDDY™ uses standard alkaline AA batteries for operation. Under normal operating conditions, used once or twice a week, the batteries will last for at least 6 months. A low battery warning is displayed before the user starts a data collection. The user can also test the module’s current battery condition at any time. The scanned data is stored in Non-Volatile Memory and is not dependent on battery voltage, and therefore is not lost when the batteries are removed to be replaced.
Does it record airflow?
No. AUDIT-BUDDY™ does not measure airflow. However, our software programs - AUDIT-MATE 2.0 - utilize the temperature data to calculate airflow inefficiencies, such as bypass and recirculation, as well as the required CFM necessary to effectively cool an aisle or room.
Can I integrate AUDIT-BUDDY information into my Building Management System?
All collected data from Purkay Labs Software and Macros support data export in .CSV and .PNG formats. Specific integration to a building automation system will require a custom wrapper to be written. This will vary from site to site based on the specific requirements. Please contact Purkay Labs for more information.

“AUDIT-BUDDY allowed us to reduce the amount of time required to get accurate readings compared to alternative methods and tools used in the past. ”
— Greg Dumas, Construction Operations Manager
“I have used the Audit Buddy and it is a great tool to add to your critical facility. It is an inexpensive tool that monitors and records temperature and humidity that you can review and then make changes and test again to see the results and these changes within a short amount of time. This is a great product and I highly recommend getting it for your facilities.
