Tech Inspections – LDARtools

What this report does

Shows the number of M21 (EPA Method 21) and OGI (Optical Gas Imaging) inspections each technician performed each day during the selected date range, along with the first and last inspection times for the session and the analyzer or camera used. One row represents one day of work for a single technician on a single instrument.

Use this report to review technician productivity, confirm inspection counts per day, and compare session durations across technicians or time periods. This report is available directly on the Reports tab.

When to use it

Reviewing how many components each technician inspected per day.
Identifying unusually short or long inspection sessions.
Confirming which analyzer or camera a technician used on a given date.
Comparing inspection throughput across the team.

What's included and excluded

Included:

M21 inspections — grouped by technician, analyzer, date, and probe type.
OGI inspections — grouped by technician, camera, and date.

Excluded:

AVO inspections.
Cooling Tower inspections.
Any inspection type other than M21 and OGI.

How key values are calculated

One row per session

A "session" is defined as a unique combination of technician + analyzer (or camera) + date. If a technician used two different analyzers on the same day, they produce two rows. If a technician switched between Standard and Extension probe on the same day with the same analyzer, they produce two rows.

Inspections

The count of individual inspection records for the session. Each component inspection is one record.

Start and Final

The earliest (Start) and latest (Final) DatePerformed values within the session, converted to the local time zone of the component inspected.

Probe Type

Applies to M21 inspections only. "Extension" indicates the extension probe was used during the session; "Standard" indicates the standard probe. OGI sessions leave this column blank.

Tips and common questions

"Why is Probe Type blank for some rows?" Blank Probe Type means the row represents OGI inspections, which do not use a probe. M21 rows always show either "Standard" or "Extension."
"A technician has two rows for the same date." The technician used more than one analyzer on that date, or switched between probe types with the same analyzer. Each combination of technician + analyzer + probe type produces its own row.
"Why doesn't the report let me filter by technician or unit?" This report covers the full picture of inspection activity for the date range. To focus on a specific technician or unit, export to Excel and filter there.
"Start and Final are the same time." The technician performed only one inspection during the session, so the earliest and latest times are identical.
"AVO inspections are not showing." AVO inspections are excluded from this report. Only M21 and OGI inspection types appear.
"The report comes back empty." No M21 or OGI inspections were recorded during the selected date range. Confirm that inspection records for the period have been entered in Chateau.
"AVO technicians are not appearing in this report." This report covers instrument-based inspections only — M21 (Method 21) and OGI (Optical Gas Imaging). AVO (Audio, Visual, and Olfactory) inspections are not instrument-based and are not included. To review AVO inspection activity by technician, use the AVO Inspections report.
"A technician appears on two rows for the same date." A technician who switches probe types during a shift will appear on a separate row for each probe type used. For example, a technician who used both a standard probe and a high-flow probe on the same day will have two rows, each showing the inspection count for that probe configuration. This breakdown is intentional — it allows you to see the scope of work performed with each probe type separately.

Sample output

Report run for Example Facility, StartDate: 5/1/2024, EndDate: 8/13/2024.

What the rows illustrate:

George Smith (5/7/24) — single Start time displayed without PM: 53 inspections with Start showing "5/7/24 4:43" and Final showing "5/7/2024 4:43 PM" — the same time, indicating a single-inspection session or all inspections recorded at the same timestamp.
George Smith (5/12/24) — highest single-day count: 250 inspections from 7:59 AM to 3:59 PM, an 8-hour session and the largest inspection count in the sample.
George Smith (5/16/24 and 5/17/24) — minimal sessions: 2 inspections on 5/16 and 1 inspection on 5/17, each in under 15 minutes. Single or near-single inspection sessions are valid rows and do not indicate a reporting error.
George Smith (6/3/24, analyzer phx42-1373) — analyzer switch: George Smith's first five rows all use analyzer phx42-2036; on 6/3/24 he appears with analyzer phx42-1373 for 125 inspections.
George Smith and Larry Johnson on 6/3/24 — two technicians, same date: Both technicians worked on 6/3/24 using different analyzers (phx42-1373 and phx42-2036 respectively), each appearing as a separate row. Larry Johnson's session ran from 14:21 to 6:21 PM (42 inspections); George Smith's from 12:53 to 15:53 (125 inspections).
