V-PRO Product Page and Ad

A detector is only safe if it gets carried

The V-PRO couldn't out-brand Honeywell, and on specifications it could lose to other makers. It could beat every comparable detector on weight — 360 g against a typical 700 g. I built its product page and a magazine ad on that one claim.

THE 45-SECOND READ

PROBLEM

On paper, the V-PRO is one more handheld PID (VOC) detector. Against Honeywell and other established names it loses on brand credibility, and on specifications it could lose to other makers. A feature list would put it in a comparison it can't win.

DECISION

Find the one thing it beats every comparable detector at — weight — and build everything on it. Then tie the weight to a real problem — inspectors leave heavy detectors behind — so being light means being safe.

PRODUCT

A long-scroll product page that argues one claim from top to bottom, and a magazine ad that carries the same claim to print.

STATUS

The page was live on the company website; it was taken down after I left and no one was maintaining it. The ad ran in an industrial-safety magazine.

On brand, Honeywell wins. On specs, someone else might. The V-PRO needed a way in — and the one comparison it won against every rival was weight.

THE POSITIONING PROBLEM

Pick the fight you can win

Weight became the headline instead of one feature in a list. But a number only sells if it solves something, so the page and the ad both name the problem first: older PID detectors weigh around 700 g and don’t last a shift, so inspectors leave them behind. “It’s the tool, not the people.”

One argument, top to bottom

  1. The top of the page: "360g 的安全感" (the safety of 360 g) over a photo of a worker holding the detector, then a strip with 30 hours, 4 ranges and a 2-year warranty.
    01

    Open on the claim

    "360 g" is the headline, with three numbers directly underneath — a 30-hour battery, 4 measurement ranges, a 2-year warranty. The product name is a small kicker; the claim comes first.

  2. The problem section: "「檢測到異味時,已經來不及了。」" (by the time you can smell it, it's too late), with a paragraph on 700 g detectors that don't last a shift.
    02

    Name the problem

    "By the time you can smell it, it's too late." Older PID detectors weigh around 700 g and don't last a shift, so inspectors leave them behind. The page says it plainly: the tool, not the people. That turns being light into a safety argument.

  3. The section headed "比一杯大杯拿鐵還輕,卻能守護一整個班次" (lighter than a large latte, yet it covers a whole shift). A balance scale holds a paper coffee cup on one side and the detector on the other.
    03

    Make the number felt

    "Lighter than a large latte, yet it covers a whole shift." 360 g is abstract; a coffee is something everyone has held. The balance scale shows the comparison, and four tags sum up the case — 360 g, 30 hours, app trend charts, one-tap export.

  4. The selection guide: "4 量程分工策略" with four range cards — 0–4,000 ppm, 0–10,000 ppm, 0–40 ppm and 0–3,000 ppb — each listing the jobs it suits and its resolution.
    04

    Choose by the job

    Four models instead of one compromise — "選對量程,才有準度" (choose the right range to get accuracy). Each card lists named jobs, from general plant rounds at 0–4,000 ppm to cleanroom trace monitoring at 0–3,000 ppb.

  5. A comparison table, "與市面常見手持式 PID 比較": V-PRO against common handheld PIDs on portability, battery, data logging, app and range strategy.
    05

    Compare with the category

    A side-by-side with common handheld PIDs — the category, not a named rival — on weight, battery, logging interval, app and range strategy.

  6. The spec sheet — detection principle, 360 g with battery, 30-hour battery, IP67, operating temperature, BLE and IR Link, IECEx / ATEX, 2-year warranty — followed by a dark contact block offering an on-site demo and a quote.
    06

    Specs last, then the ask

    The full spec sheet comes after the argument, as proof rather than as the pitch. The page closes on a free on-site demo and help choosing a model.

The same page at phone width

The portfolio copy keeps the page’s original layout and copy, with the product photos it used. On a phone the sections reflow into a single column; the order of the argument stays the same.

The same claim, in print

The V-PRO magazine ad. Left half: an orange and a yellow detector on black above the name V-PRO. Right half: the headline, the problem line, "360 g*" beside "競品平均 700g 以上†", four range bars, certification badges, two footnotes, and two QR codes.
THE AD AS IT RAN IN AN INDUSTRIAL-SAFETY MAGAZINE — 196 × 136 MM WITH BLEED
  1. 01The headline names the outcome

    "巡檢帶得動,才叫安全。" — it's only safe if inspectors will carry it.

  2. 02The problem, in one line

    Nearly the same sentence as the web page — heavy detectors with short batteries get left behind; it's the tool, not the people.

  3. 03The claim, in orange

    360 g, with an asterisk — the weight varies by model and configuration.

  4. 04The comparison, sourced

    "Competitor average 700 g or more" carries a dagger — compiled from the public specs of common pumped PID detectors.

  5. 05Four ranges in two rows

    The page's four ranges, in two rows.

  6. 06Certifications as plain badges

    IECEx, ATEX, IP67, intrinsically safe, made in Korea.

  7. 07Both footnotes, in print

    Every comparative number in the ad is qualified where it appears.

  8. 08A QR code for the specs
  9. 09A QR code for the next step

    LINE, for a catalog, a quote or a trial — the ad ends in an action, not a slogan.

Print from the same tools

The ad was built in HTML and CSS, like the product page, and exported from Chrome to a print-ready PDF with bleed. One toolset for the pages and the print meant a one-person team could produce both.
