RaySafe 452 Radiation Survey Meter — Auction Analysis

This RaySafe 452-family meter has two visible interchangeable lids, strongly supporting a Full configuration, but the exact part number, calibration-matched lid pairing, current calibration, battery health, and radiation response are not established. With no preserved auction bid, the $750 blind ceiling supports REVIEW only.

Why this decision

REVIEW: the $750 blind ceiling is defensible only on a $2,500 visual-only resale basis and cannot be compared with an invented auction price; exact version, lid pairing, calibration, and functional evidence require verification.

What to verify before bidding

  • Two lids strongly support Full configuration but do not confirm the exact Full part number.
  • The visible lids are not established as calibration-matched to this meter.
  • No self-test, battery, software, measurement, alarm, or reference-response evidence is supplied.

Auction snapshot

The September 1, 2026 research record does not preserve a reliable immutable bid or scheduled close. This page preserves the observed evidence without inventing a live auction state.

A current-looking specialist radiation meter still depends on exact model, lid configuration, calibration pairing, battery, and measurement evidence.

    The original CALIBRATED state exceeded the preserved photo evidence. The page's dated narrative already says current calibration of this meter and lid pair is unproven.

How evidence is classified

Seller facts, photo-derived observations, manufacturer context, unknowns, and LotCaliper assumptions remain explicitly separated.

Source Confirmed

Seller-confirmed

  • One RaySafe 452-family survey meter is visible with one mounted and one loose interchangeable lid.
  • Two lids strongly support the higher-function Full configuration; current manufacturer materials retain the 452 family and RaySafe View support.

Photo Derived

Photo-derived

  • The enclosure, handle/control pad, detector exterior, mounted lid, and loose lid appear intact with ordinary institutional wear.
  • The display is off; fitted foam and stored lids do not prove calibration pairing or working condition.

Not Established

Not established

  • Exact Full part number, individual lid types, calibration-matched pairing, current calibration, certificate, charger/case completeness, battery condition, and software connection.
  • Power-on, self-test, dose or air-kerma response, counter mode, alarm, reference/background response, observed bid, scheduled close, and final outcome.

Manufacturer Context

Independent context

  • RaySafe distinguishes Full, Ambient, and Air Kerma 452 configurations and calibrates each meter with its specific lid or lids.
  • RaySafe service guidance requires both Full-version lids to accompany calibration; two visible lids do not establish that this meter/lid combination is calibration-matched or currently calibrated.
  • Current replacement and procurement figures demonstrate product continuity but are not used-market resale values.

Lotcaliper Assumption

LotCaliper assumptions

  • $2,500 conservative visual-only specialist resale with two visible lids but no function or current-calibration premium.
  • $750 blind maximum hammer after shipping, functional/calibration reserve, accessory/pairing, selling, profit, and uncertainty reserves.

RaySafe 452 configuration, calibration pairing, and bidding economics

The two visible lids are meaningful positive configuration evidence. They do not justify silently assigning manufacturer kit 5082301 or treating either lid as calibration-matched without readable labels or records.

The model discounts current tested-used, government-procurement, and new-kit context because the auction unit has no demonstrated startup, battery, radiation response, or current calibration.

  • Verify readable model and lid labels, pairing records, calibration dates, and a current certificate before applying Full-version or calibrated value.
  • Demonstrate startup, self-test, battery, RaySafe View communication, and appropriate reference/background response before using tested-market context.

Recommendation and rationale

Market support assesses how well the available evidence supports the resale assumption. Exact third-party marketplace records may be omitted when source-use rights are unclear. Each dimension uses the published methodology rubric; a confidence label measures the strength and boundedness of its evidence, not the likelihood of a profitable outcome.

Risks and unknowns

High · Model Variant Unresolved

Two lids strongly support Full configuration but do not confirm the exact Full part number.

The narrower Ambient and Air Kerma variants have different functionality.

High · Calibration Pairing Unverified

The visible lids are not established as calibration-matched to this meter.

RaySafe calibrates the instrument with its specific lids.

High · Radiation Response Unverified

No self-test, battery, software, measurement, alarm, or reference-response evidence is supplied.

Cosmetic condition cannot prove specialist measurement performance.
