Get Data

Stream data directly to the WIFI-MATE program.

Put Away

Once you’re done, put your AUDIT-BUDDY away. There is no installation required.


The Tool


What is Audit-Buddy?

AUDIT-BUDDY consists of 3 Temperature and Humidity Modules (TH1) and an adjustable carbon fiber rod.


Smart Design

Place AUDIT-BUDDY perpendicular to the cabinet. The multi-level placement captures the air profile simultaneously.


How it Works

With three custom scan modes, AUDIT-BUDDY can target specific problem areas with little hassle.


Baseline Your Environment

The QuickScan mode takes 20 second scans to baseline your environment. Use this data to create vertical or horizontal heat maps.

Track Problems Over Time

The LongScan mode takes user-defined trend data in a single location.

Diagnose Airflow Issues

Use two stands to track the inlet and outlet temperatures over time.  This measurement can be used in two ways. First, when compared to the CRAC settings, you can quantify how much cold supply air reaches the server and how much is being wasted. Second, when compared to the kW information, you can determine how much CFM is required.

Use this mode to diagnose what’s causing your hot spots and overcooled areas.  



The Data

AUDIT-BUDDY 2.0 uses the WIFI-MATE program stream real-time environmental data.

+ What is AUDIT-BUDDY?

AUDIT-BUDDY is a portable and standalone temperature and humidity monitor. It consists of three temperature and humidity sensors and 1 carbon fiber rod with weighted base. It is portable, battery powered and has a low learning curve— no new programs/installations--- just scan and use Excel to view data. The key advantage is that AUDIT-BUDDY can spot check air quality and diagnose cooling issues in areas without permanent monitoring.

+ How does AUDIT-BUDDY compare to other environmental monitors (wireless sensors, IR guns, DCIMs)?

AUDIT-BUDDY™ is a tool aimed at transient monitoring applications with no demands on the existing infrastructure. Users can deploy AUDIT-BUDDY™ where they suspect a problem, or if they need to baseline their facility, then put AUDIT-BUDDY™ away, without leaving any footprint in the datahall.

Wireless sensors require monitoring infrastructure to be set-up to collect information and users must keep track of where the sensors are located, adding to the RF pollution in the white space.

Infrared guns are not, and cannot, be as accurate as AUDIT-BUDDY™. Infrared guns can only measure the temperature of the surface of the server and can’t measure true air temperature. In addition, the color of the reflecting surface affects the temperature measurement. If you are assessing data center operating efficiency by minute changes in the CRAC settings, where 1°F change is significant, you really can’t measure that impact with an IR gun. AUDIT-BUDDY™ on the other hand is an accurate tool to measure such minor change impacts.

+ How does AUDIT-BUDDY compare to other data loggers?

AUDIT-BUDDY, like many data loggers such a measure both temperature and relative humidity. However, AUDIT-BUDDY differs in its standalone design and ability to both record and diagnose data.

The construction of Audit-Buddy allows you to measure the inlet or outlet air going into the server at three different heights simultaneously. This provides an accurate account of the whole rack environment, rather than an individual point. Measurement of the air temperature going in or out simultaneously of the server is key, as it lets you determine your cooling efficiency. Stated another way, the Audit-Buddy system provides you temperature stratification information for your cold and hot aisles without requiring any special installation, without touching the server or hanging multiple sensors from the ceiling.

The second key difference is with the information supplied. The Audit-Buddy system tells you what's causing your thermal issues (hot spots, overcooled regions etc.), how effective your cool efficiency is, and how much cold air you're wasting due to bypass and recirculation airflow. Our software is designed to make it easy to quickly post-process data, without wasting a lot of time. Audit-Buddy is a data center application focused tool that provides information about the cooling system, not just the raw data.

+ What type of data do I get with AUDIT-BUDDY?

AUDIT-BUDDY records temperature and humidity per location and the different software allows the users to easily manipulate the data into meaningful information. A basic list of data functions is provided below: • Quickly collect data for every cabinet environment • Collect Long term trend data for a single stand • View Scan highlights • View time-trend graphs with customized alarm limits • Create “CFD-like" vertical heat Map with real-time data. • Diagnose server specific cooling efficiency • Calculate cost of “overcooling” in terms of OpEX and Consumption • Create Interactive “aerial” Data Hall Views to quickly drill down and isolate problem areas

+ Does AUDIT-BUDDY measure airflow?

No. AUDIT-BUDDY does not measure airflow. However, our three software programs- the Optimize Macro, WIFI-MATE and/or Data Hall Program- 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.

+ How close and where do I place the sensors?

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.

+ How long is AUDIT-BUDDY’s battery life?

AUDIT-BUDDY uses standard alkaline AA batteries for operation. The low power design allows the user to operate the unit without requiring frequent replacements. 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.

+ How do I transfer data?

AUDIT-BUDDY design allows you to transfer data one of three ways. The simplest is using a USB Flash Drive to transfer the data after the sampling is complete. For facilities where USB Flash Drives aren’t allowed, one can use the supplied USB cable to directly download the data from the module to the PC/tablet using the AUDIT-MATE PC program. The third approach uses the 802.11 WIFI. One needs to add a WIFI Adapter Module to make the TH1 module communicate via WIFI. The sampled data is automatically streamed directly to your PC or Tablet.

+ Can I integrate my data with my Building Automation 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.
